Steam & Cinnamon Rolls
Humid Proofing, Steam Assisted Baking, Fully Steamed Rolls, and When the Dough Should Be Designed for It
Steam can be incredibly useful when making cinnamon rolls, but “using steam” can describe several completely different processes.
A pan of hot water used while dough proofs is not doing the same job as steam injected into a combi oven during baking. Neither method produces the same result as cooking the rolls entirely with steam instead of baking them.
That distinction matters because steam can be used to prevent the dough from developing a dry skin during proofing. Create a softer baking environment during the first part of the bake. Delay surface drying and crust formation. Improve expansion in certain formulas. Produce a completely crustless, steamed cinnamon roll. Refresh already-baked rolls during reheating.
These methods are related, but they are not interchangeable. A standard cinnamon roll recipe may work beautifully with humid proofing, need a few adjustments for steam assisted baking, and perform poorly when fully steamed.
“Steaming Cinnamon Roll Dough”
There are three primary categories of steam use in cinnamon roll production.
Humid proofing: The dough is not being cooked by steam. Humidity is jsut used to prevent the surface from drying out while the rolls rise. The recipe usually does not need to be reformulated for this method.
Steam-assisted baking: The rolls are still baked in an oven, but steam or added humidity is used during part of the baking process. Its main purpose is to delay crust formation, keep the surface flexible longer, and create a softer bake. Some recipes work well with steamassisted baking as written, and others might need adjustments to the filling, hydration, baking temperature, or finishing stage.
Fully steamed cinnamon rolls: The rolls are cooked entirely with steam rather than baked in dry oven heat. This produces a moist, pale, crustless sweet roll that is closer to a filled steamed bun than a traditional browned cinnamon roll. A recipe will usually perform best when it has been intentionally formulated for steaming.
There are also hybrid methods, including covering the pan during part of the bake, steaming the rolls first and browning them afterward, or reheating already-baked cinnamon rolls with steam. Before deciding whether steam will improve a cinnamon roll, you first have to decide which of these results you are actually trying to achieve.
What Steam Does to Dough
Bread dough changes dramatically when heat is applied. The gases inside the dough expand. Yeast remains active briefly before heat stops fermentation. Butter melts. Proteins begin to set. Starch absorbs available water, swells, and gelatinizes. Eventually, enough of the internal structure becomes fixed that the roll can hold its shape after cooling.
Steam changes the rate and location at which some of these transformations occur.
Steam transfers heat efficiently
When water vapor reaches the cooler surface of dough, some of it condenses. Condensation transfers heat to the dough efficiently, causing its surface temperature to rise rapidly.
This is one reason steam can accelerate the early heating of bread products. Steam-assisted products may therefore bake differently from products placed into a dry oven, even when the oven display shows the same temperature.
Steam is not jsut “adding water.” It changes heat transfer as well as moisture loss.
Steam delays surface drying
In a dry oven, water begins evaporating rapidly from the surface of the dough. As that surface loses moisture, it becomes increasingly firm and eventually forms a crust.
In a humid oven, the difference in moisture concentration between the dough and the surrounding air is smaller. Surface evaporation slows, which allows the outside of the roll to remain flexible longer.
Research on steam injection during bread baking has found that the amount of steam can affect surface starch gelatinization, crust permeability, gloss, color, mechanical strength, and the protein-starch network at the surface.
For cinnamon rolls, keeping the surface flexible can allow the dough to continue expanding before the exterior becomes firm.
That does not mean that more steam always creates more volume. Proofing, dough strength, roll size, filling weight, and steam intensity still have to remain balanced.
Steam promotes surface starch gelatinization
Starch gelatinization requires both heat and available water. As starch granules heat in the presence of water, they swell and contribute to the structure of the finished crumb.
Steam can encourage gelatinization at the surface before that surface becomes dry. This is part of the reason steamed breads can have a smooth or slightly glossy exterior rather than a dry, floury crust.
Steam suppresses or delays browning
Maillard browning and caramelization become much more pronounced once the surface becomes dry enough to rise well above the boiling point of water.
During full atmospheric steaming, the moist surface remains near the temperature of the surrounding steam, approximately 212°F or 100°C at sea level. It therefore does not develop the same browned crust as dough baked in a much hotter, dry oven.
This is why fully steamed cinnamon rolls remain pale. Steam-assisted baking is different. Once the steam is vented and the surface dries, the roll can continue heating and begin to brown.
Steam does not automatically create a moist roll for several days
Steam can reduce moisture loss during cooking, but it does not replace good formula development.
A cinnamon roll can be steamed and still become firm after cooling. Starch retrogradation, moisture redistribution, overcooking, insufficient enrichment, storage conditions, and reheating all affect softness. The method of cooking is only one part of shelf-life development.
Humid Proofing
Humid proofing is probably the most broadly useful application of steam for cinnamon rolls. The dough is not being steamed or cooked. Humidity is simply being added to the proofing environment so that the exposed surface does not dry out.
surface drying is a problem
When shaped rolls proof in dry air, the exposed dough can form a thin skin.
That skin might
Restrict expansion.
Tear as the roll rises.
Create dry lines around the spiral.
Make the surface look dull or uneven.
Cause the outside of the roll to set differently from the center.
Interfere with egg wash or other finishes.
Leave the outer edge tougher after baking.
This becomes more noticeable when rolls are proofed uncovered, when air conditioning or forced air is blowing across them, or when the final proof takes a long time. Professional proofing cabinets commonly combine warmth and humidity specifically to reduce surface drying. Published commercial recommendations vary by product and process, but controlled proofing environments frequently operate somewhere around 70% to 90% relative humidity.
Humid does not mean wet
When the surface becomes visibly wet, the environment may be too humid, the steam may be condensing directly onto cold dough, or the rolls may be sitting too close to the steam source.
Excess condensation can cause
A slick or gummy surface.
Filling residue to run across the dough.
Poor adhesion between spiral layers.
Blistering or uneven patches.
Diluted egg wash.
Excess sticking to liners or pans.
A fragile surface that wrinkles during baking.
My preferred proofing temperature for enriched cinnamon roll dough
For many enriched cinnamon roll formulas, I prefer a controlled but moderate final-proof temperature rather than an aggressively hot proof box.
A useful starting range is approximately 75°F to 82°F, depending on the formula, yeast level, dough temperature, butter content, and production schedule.
There are commercial processes that proof hotter than this, but warmer is not automatically better.
Very warm proofing can
Melt or soften butter excessively.
Cause the filling to liquefy before baking.
Accelerate fermentation faster than the dough structure can support.
Produce a roll that looks large but has weak internal structure.
Increase separation between the dough and filling.
Make timing much less forgiving.
The proofing environment must be appropriate for the specific dough rather than copied from a general bread setting.
Should cinnamon rolls be covered in a humid proofer?
They can be proofed uncovered in a properly controlled humid cabinet. That is one of the advantages of the equipment. But there is no rule that they must be uncovered.
Covering may still be useful when
The proofing equipment cycles inconsistently.
The fan is strong.
The rolls are proofing for an extended period.
The dough entered the proofer very cold.
The surface is still drying despite the humidity setting.
In a home kitchen, lightly greased plastic wrap, a reusable pan cover, or a fitted lid is often more reliable than trying to create a highly humid room.
Creating a humid proofing environment at home
A turned-off oven with a separate pan of hot water can create a warm, humid environment.
The water should warm the enclosed space gradually. The dough should not sit directly above aggressive steam, and the oven should not be turned on and allowed to become hot around the dough.
A home proofing setup should be checked with a thermometer. An oven that feels slightly warm to your hand may be much warmer than expected.
Do not assume that a “proof” setting is suitable for every cinnamon roll formula. Some proof settings run warm enough to soften butter and filling significantly.
Does the recipe need to be written for humid proofing?
Usually, no. Most cinnamon roll formulas can benefit from protection against surface drying. Humid proofing changes the environment more than it changes the fundamental cooking method.
You may need to adjust proofing time because the dough surface remains more extensible and the temperature may be more consistent, but the flour, liquid, fat, sugar, and egg percentages do not usually need to change simply because humidity is present.
Steam-Assisted Baking
Steam-assisted baking combines oven heat with controlled humidity. The rolls are still baked, but part or all of the baking environment contains steam.
This may be done in
A commercial rack or deck oven with steam injection.
A combi oven.
A residential combi-steam oven.
A covered pan that traps the dough’s own moisture.
A conventional oven with a carefully managed steam source.
Steam-assisted cinnamon rolls can still brown. The result depends on the oven temperature, steam intensity, duration of steam, airflow, pan, and whether the oven is vented during the final part of the bake.
What steam-assisted baking can do for cinnamon rolls
Keep the tops softer.
Delay early crust formation.
Allow additional expansion before the exterior firms.
Reduce dry edges.
Produce a softer transition between the outside and center crumb.
Help large rolls bake through before their tops become excessively dark.
Create a more humid pan environment without pouring liquid directly over the rolls.
This can be especially useful for bakery-style pull-apart cinnamon rolls where the goal is a soft top and minimal crust.
When steam may not be desirable
Steam assisted baking is not automatically an upgrade. It may work against you when you want:
Deeply browned tops.
Crisp or caramelized edges.
A firm exterior capable of holding heavy icing.
Distinct laminated or flaky layers.
A dry enough surface for strong roasted flavor.
Significant caramelization from the filling around the bottom and edges.
Steam percentage is not universal
One oven’s “30% steam” is not necessarily equivalent to another oven’s “30% steam.”
Chamber size.
Steam generation.
Venting.
Fan speed.
Sensor location.
Recovery after loading.
Whether the percentage represents relative humidity, steam injection time, or a proprietary control system.
This is why combi-oven settings should be treated as equipment-specific programs rather than universal formulas. For example, Anova publishes a cinnamon roll program using 60% steam for proofing and 40% steam at 356°F for baking. Thermador publishes a separate cinnamon roll method using steam convection at 325°F. These are both valid equipment-specific approaches, but the numbers cannot automatically be transferred to every oven.
A practical two-stage starting point
For an existing cinnamon roll recipe, I would begin development with a restrained two-stage program rather than immediately using heavy steam for the entire bake.
Stage one: Expansion and setting
Use low to moderate steam during the early portion of baking. The main objeticv is to keep the surface flexible while the rolls expand and the internal structure begins setting.
Stage two: Venting and finishing
Reduce or remove steam and allow the oven to vent.
Dry the surface.
Develop color.
Strengthen the exterior.
Finish setting the center.
Prevent the roll from remaining wet or rubbery.
For many medium-to-large cinnamon rolls, a starting test could involve steam during approximately the first one-third to one-half of the bake, followed by a dry finish.
That is a development starting point, not a universal program.
The appropriate changeover point depends on roll size, pan depth, dough richness, filling moisture, and the oven itself.
Should the oven temperature be lowered?
Possibly. Because steam changes heat transfer and reduces evaporative cooling, a combi-steam oven may cook the product more efficiently than the dry oven in which the original formula was developed.
When converting a recipe, I would test
The original temperature.
A temperature approximately 15°F to 25°F lower.
An earlier doneness check.
A dry finishing stage if color is insufficient.
Do not lower the temperature automatically without evaluating the result. A temperature that is too low may extend the bake, increase filling leakage, and leave the rolls pale or weak.
Should the recipe be redesigned for steam-assisted baking?
Not always. A standard enriched cinnamon roll recipe can often be baked successfully with moderate steam. However, a formula developed specifically for a humid bake may perform more consistently.
The areas most likely to require adjustment are the filling, hydration, roll size, pan arrangement, and final baking program.
Dough hydration
Steam reduces surface moisture loss, but it does not pump large amounts of water into the center of the dough.
Still, an already very wet dough may remain excessively soft when baked in a humid chamber. A formula developed for a dry convection oven may rely on evaporation to produce its final structure.
Before lowering the dough hydration, first test
Less steam.
Earlier venting.
A longer dry finish.
A shallower pan.
More space between the rolls.
Dough strength
Steam can allow greater expansion before the surface sets. That is only useful when the dough has enough strength to retain the expansion.
An underdeveloped or overproofed dough may inflate rapidly and then collapse.
Steam cannot correct poor gluten development, excessive fermentation, or a formula that lacks sufficient structure.
Sugar
Sugar holds water and raises the temperature at which starch gelatinization occurs. Studies of wheat starch and bread dough have shown that sugar can increase gelatinization temperature by reducing available water and altering starch behavior.
This matters in rich cinnamon roll dough because the center must become hot enough, for long enough, to set around a sugary filling.
High sugar does not make steam baking impossible. It means that a pale, soft exterior cannot be your only indicator of doneness.
Filling
The filling is often the first part of the formula to reveal that too much steam is being used. Butter melts. Sugar dissolves. Water moves between the dough and filling. If the dough remains very soft while the filling becomes fluid, the spiral layers can slide apart.
A steam-friendly filling should be cohesive rather than watery.
It may help to
Use softened butter rather than melted butter.
Avoid adding unnecessary liquid.
Include a small amount of flour, starch, milk powder, cookie crumbs, or another dry binder when appropriate.
Avoid an excessively thick layer of filling.
Leave a small clean edge for sealing the log.
Chill the shaped rolls briefly when the filling becomes too fluid during production.
A binder should not be added solely because steam is present. It should be added when testing shows that the filling is escaping, separating, or preventing the dough from setting.
Pan choice
A deep pan packed tightly with large rolls creates a highly humid environment on its own. Adding aggressive oven steam may make the center slow to set while the outside rolls continue cooking against the hot pan walls.
When testing steam-assisted baking, compare
Light-colored aluminum.
Dark metal.
Glass or ceramic.
Shallow versus deep pans.
Touching versus slightly spaced rolls.
Can I create steam in a conventional home oven?
Yes, but it is harder to control. A pan of hot water can raise humidity, although the effect varies significantly between ovens. Some ovens vent moisture quickly. Others retain it.
Before adding water to an oven, check the manufacturer’s instructions. Do not pour water directly onto the oven floor, heating elements, glass, or any surface not designed for it.
For cinnamon rolls, covering the pan loosely during the first portion of baking is often safer and more repeatable than trying to fill a conventional oven with steam.
Foil or a fitted lid traps moisture released by the rolls themselves, creating a local humid environment.
The cover must then be removed early enough for the tops to dry, strengthen, and color.
Is pouring heavy cream over cinnamon rolls the same as steaming?
No. Heavy cream adds water, fat, milk solids, and lactose directly to the pan.
It can create additional moisture and local steam as it heats, but it also changes
The filling concentration.
The bottom texture.
The richness.
The browning.
The sauce surrounding the rolls.
The dough’s exposure to liquid.
Steam changes the oven environment. Heavy cream changes the formula. They should not be treated as interchangeable techniques.
Fully Steamed Cinnamon Rolls
Fully steamed cinnamon rolls are cooked with steam vs baked in dry oven heat. The result is closer to a sweet steamed bread or filled bun than a traditional American bakery cinnamon roll.
That does not make it inferior. It makes it a different product. Well-made steamed bread is known for a pale, smooth exterior and a soft, moist, uniform crumb.
A steamed cinnamon roll can be exceptionally tender, but it will not naturally develop the browned crust, toasted butter flavor, or caramelized filling associated with an oven-baked roll.
What a fully steamed cinnamon roll should be
A successful fully steamed roll should be
Soft but not wet.
Set through the center.
Flexible without being rubbery.
Moist without appearing raw.
Stable enough to hold its spiral.
Smooth or gently rounded on top.
Pale unless color is added by ingredients.
Easy to pull apart without leaving gummy dough behind.
What it should not be
A standard raw cinnamon roll placed in a steamer with no testing.
Saturated with condensation.
Collapsed after cooling.
Surrounded by a pool of melted filling.
Dense at the center.
Rubbery from excessive steaming.
So rich that the dough cannot set properly.
Should a Fully Steamed Cinnamon Roll Use a Special Dough?
In most cases, yes. You can steam a traditional cinnamon roll formula as an experiment, but a recipe designed for dry baking may rely on high oven heat and moisture evaporation to create its intended structure. A very rich brioche-style dough may contain substantial butter, egg, sugar, and milk solids. During dry baking, those ingredients contribute to browning, aroma, crust development, and tenderness.
During full steaming
There is little surface browning.
Butter still melts.
Sugar still attracts water.
The dough loses less moisture.
The filling remains fluid longer.
The exterior does not form a strong baked crust.
The final crumb may feel heavier than expected.
A steamed cinnamon roll formula will often perform better when it is somewhat less rich, slightly firmer, and structurally cleaner than a formula created for a deeply browned baked roll.
Flour selection
Steamed bread does not always benefit from the strongest possible flour. Extremely strong flour may create a chewy, elastic texture rather than a soft, fine crumb. Very weak flour, however, may not support the spiral and filling. A moderate-protein all-purpose flour is a practical starting point.
Bread flour may still be appropriate when
The filling is heavy.
The rolls are large.
The formula contains significant fat or sugar.
The dough requires more structural tolerance.
The rolls will be frozen or handled extensively.
Hydration
Do not assume that the highest-hydration milk bread dough will produce the best steamed cinnamon roll. Full steaming limits surface dehydration. A dough that feels beautifully soft when baked may become sticky, gummy, or difficult to set when steamed.
I would begin with a manageable, moderately soft dough that can
Be rolled cleanly.
Hold a defined spiral.
Support the filling.
Proof without spreading.
Release cleanly from parchment.
Sugar level
A fully steamed cinnamon roll still needs to taste like a sweet roll, but it may not need as much sugar in the dough as a baked formula.
Because there is no deeply browned crust, excessive sweetness can feel more pronounced and less balanced.
High sugar also raises starch gelatinization temperature and can slow fermentation by reducing available water. That combination can contribute to a center that takes longer to set.
For early testing, I would keep the dough moderately sweet and allow the filling or glaze to provide additional sweetness.
Fat level
Some fat improves tenderness and eating quality.
Too much fat can weaken the dough and increase layer separation as the rolls heat. Because the steamer does not create a firm crust, the dough must hold itself together without relying on a browned exterior.
I would begin with moderate enrichment rather than a very high-butter brioche.
Eggs
Eggs can provide richness, emulsification, color, and protein structure.
However, a high proportion of egg can also make a steamed roll taste more custardy or produce a firmer, more elastic crumb.
Eggs are optional. A milk-based dough with a moderate amount of butter or oil can produce a very soft steamed result.
Tangzhong or yudane
Pregelatinized flour methods can improve water retention and softness, but they should not be stacked thoughtlessly with a high-hydration dough and full steam.
Steam already limits moisture loss. Too much pregelatinized starch combined with too much liquid can create a gummy or almost pudding-like line in the center of the roll.
When using tangzhong or yudane:
Start conservatively.
Keep the final dough easy to shape.
Evaluate the rolls after complete cooling.
Check the texture again the following day.
Reduce either the cooked flour portion or total liquid if the crumb remains tacky.
Designing the Filling for a Fully Steamed Roll
The filling must survive melting without destroying the spiral. A traditional mixture of butter, brown sugar, and cinnamon may work, but it may also leak heavily because the sugar and butter liquefy before the dough is fully set.
A more stable steamed-roll filling
A steamed-roll filling may benefit from
Softened rather than melted fat.
Finely ground sugar.
Cinnamon and salt.
A modest dry binder.
Less total filling than an oversized bakery roll.
A thin, even application.
Possible binders include
All-purpose flour.
Cornstarch or another starch.
Milk powder.
Finely ground cookie or cake crumbs.
Nut flour, when appropriate for the flavor and allergen plan.
The binder should absorb enough free moisture to keep the filling cohesive without making it pasty or dry.
Be careful with brown sugar
Brown sugar contains molasses and tends to produce a wetter filling than granulated sugar. That can be desirable, but a heavy layer of dark brown sugar and butter may dissolve into syrup during steaming. A blend of brown and granulated sugar can sometimes produce a cleaner spiral.
Wet fillings
Fruit preserves, cooked fruit, cream cheese, custard, and other wet fillings require additional testing.
Delay the heating of the center.
Weaken the dough layers.
Produce gaps around the spiral.
Leak onto the steamer liner.
Increase the risk of a gummy center.
Fully Steamed Cinnamon Roll Process
1. Develop enough dough strength
The dough needs enough strength to hold gas and support the filling.
That does not mean every dough requires an extreme windowpane. It means the dough should be cohesive, elastic enough to roll, and capable of retaining its shape.
A weak dough may expand during steaming and then collapse.
2. Keep the filling controlled
Spread the filling thinly and evenly.
Avoid pressing so hard that the dough is compressed. Roll the log evenly, but do not create excessive tension that squeezes the filling forward.
Seal the final edge securely.
3. Cut cleanly
Use a sharp knife or unflavored dental floss.
Very soft dough may need a brief chill before cutting.
Place each roll on parchment with enough exposed space for steam to circulate.
4. Proof carefully
Steamed rolls still need a proper final proof.
Underproofed rolls may split, become dense, or expand unevenly. Overproofed rolls may collapse when the heat changes or when the steamer is opened.
Judge the dough rather than waiting for an exact doubling.
The rolls should look aerated and visibly expanded, but they should still have enough strength to continue expanding during steaming.
5. Establish steady steam
The steamer should be producing stable steam before the rolls begin cooking unless the recipe has been specifically developed for a cold-start method.
Loading into inconsistent steam can cause uneven expansion and setting.
However, extremely aggressive steam is not necessarily better. Research on steamed bread has linked excessive steaming rates with surface defects including blisters, dimples, jelly-like spots, and shrinkage.
6. Protect the rolls from dripping condensation
Large drops of condensed water falling from the lid can damage the surface.
Use equipment designed to manage condensation. With a stovetop steamer, ensure the lid and setup direct condensation away from the product whenever possible.
The rolls need humid heat, not a shower of water.
7. Avoid opening the steamer repeatedly
Opening the lid releases heat and steam and can interrupt the setting process.
Use rolls of consistent size so the steaming time can be established during testing.
8. Confirm that the center is set
Color is not a useful doneness indicator because the rolls will remain pale.
Evaluate:
Center temperature.
Resistance when gently pressed.
Whether the spiral springs back.
Whether the center appears wet when separated.
Whether the bottom releases cleanly.
Texture after several minutes of cooling.
Baked cinnamon roll formulas often finish around the upper 180s to approximately 190°F internally, although the correct endpoint depends on the formula. King Arthur Baking, for example, lists targets ranging from about 188°F to 190°F for several soft cinnamon roll formulas.
A fully steamed formula may require its own validated endpoint. Do not assume that one temperature guarantees the correct texture for every level of sugar, egg, fat, and hydration.
9. Manage the end of steaming
Abrupt moisture and temperature changes can contribute to shrinking, wrinkling, and structural collapse.
Steamed-bread research identifies moisture migration, outer-layer shrinkage, structural weakening, and pore collapse as contributors to wrinkled surfaces.
When testing, compare:
Removing the rolls immediately.
Turning off the steamer and resting briefly before opening.
Cracking the lid gradually.
Cooling the rolls in a protected area rather than directly under a fan.
The best method will depend on the equipment and formula.
10. Cool before judging the crumb
A hot steamed roll may feel wetter and softer than it will after its starches settle during cooling.
Do not immediately assume that a soft center is raw, but do not dismiss a genuinely gummy center either.
Evaluate the rolls:
Hot.
After 20 to 30 minutes.
Fully cooled.
The next day.
After reheating.
That is the only way to understand the actual product.
Hybrid Steam First, Then Bake
A steamed-then-baked cinnamon roll can combine a soft interior with a lightly browned exterior.
The roll is first cooked partially or almost completely with steam. It is then moved into dry heat to develop color and flavor.
A very soft crumb.
Less moisture loss.
A thin rather than thick crust.
Some toasted or caramelized flavor.
A surface strong enough to support icing.
The challenge is timing. If the roll is completely set during steaming, the dry stage may only color the exterior. If it is moved too early, the dry oven must finish setting the center and may erase some of the textural difference.
The dry stage must also be hot enough to remove surface moisture before meaningful browning can occur.
A second hybrid method is to begin with steam-assisted baking and then finish in a dry oven. This is generally easier to control than fully steaming and transferring the rolls afterward.
Covering the Pan For Local Steam Control
Covering cinnamon rolls during the first part of baking traps moisture released by the dough. This creates a humid microclimate around the rolls without adding external steam.
Slow top browning.
Prevent dry edges.
Encourage more even heating.
Protect large rolls while the center catches up.
It can also cause:
Pale tops.
Excessive filling liquefaction.
Condensation dripping from the cover.
A weak or wet surface.
Longer bake times.
Remove the cover early enough to allow a proper dry finish. Covering is not identical to a combi oven, but it is one of the most practical ways for home bakers to study the effects of a humid bake.
Reheating Cinnamon Rolls With Steam
Steam is especially useful for reheating already-baked cinnamon rolls.
A small amount of humidity can soften the crumb and reduce the dry texture created by storage. However, reheating cannot permanently reverse staling. It temporarily redistributes moisture and softens crystallized starch structures. Use short reheating cycles and evaluate the center before adding more time.
For bakery service, glaze may need to be applied after steaming or reheating rather than before.
