Detailed instructions
Overall progress: 0% completed
Phase 1: Preparing the Yeast Sponge – 15 min
Appliances: Stove
1. Warm 1.06 cups of whole milk in a small saucepan over low heat until lukewarm, reaching roughly 100 °F to 110 °F. Pour the warm milk into a mixing bowl, stir in 2.00 tbsp of granulated sugar and 2.00 tsp of active dry yeast. Let the mixture sit undisturbed for 10 minutes until a foamy, active layer forms on top.
Visual check point (VKB): The yeast mixture must develop a thick, bubbly foam layer, confirming active yeast fermentation.
Before moving to the next step:
Ensure the milk is not too hot, otherwise it will kill the yeast and prevent the dough from rising.
Phase 2: Mixing and Kneading the Dough – 25 min
Appliances: Stand mixer
2. Add 1.13 lb of all-purpose flour, 0.50 tsp of salt, 1.00 piece of large egg, and 2.00 tbsp of melted unsalted butter to the foamy yeast mixture. Using a stand mixer fitted with a dough hook attachment, knead on medium speed for 10 to 12 minutes until the dough becomes smooth, elastic, and pulls cleanly away from the sides of the bowl. Cover the bowl with a clean kitchen towel and let it rise in a warm, draft-free spot for 60 minutes until doubled in volume.
VKB: The dough should be soft and slightly tacky, stretching without tearing easily when gently pulled.
Before moving to the next step:
Verify that the dough has fully doubled in size before proceeding to shaping.
Phase 3: Shaping and Filling the Buns – 30 min
Appliances: None
3. Turn the risen dough out onto a lightly floured work surface and gently press out excess gas. Divide the dough into 6 equal portions, shaping each into a smooth ball. Flatten each ball into a round disk, place 2.00 tbsp of thick plum butter in the center, and carefully pull the edges up and over the filling, pinching tightly to seal completely so no jam leaks out.
VKB: Seams must be sealed securely with no exposed filling, otherwise jam will escape during steaming.
Before moving to the next step:
Let the shaped buns rest for 15 minutes on a floured board for a secondary proof before steaming.
Phase 4: Steaming the Buns – 25 min
Appliances: Stove, steamer pot
4. Bring a large pot of water to a rolling boil over medium-high heat. Place a well-greased steamer insert or cheesecloth-lined sieve over the boiling water. Arrange the buns on the steamer, leaving adequate space between them for expansion, cover with a tight-fitting lid, and steam over medium heat for 20 minutes without lifting the lid.
VKB: Buns should swell significantly, achieving a soft, springy texture and matte appearance.
Before moving to the next step:
Do not lift the lid during the first 15 minutes of steaming to prevent the buns from collapsing.
Phase 5: Finishing and Piercing – 5 min
Appliances: None
5. Remove the buns from the steamer immediately after cooking. Carefully pierce each hot bun once with a toothpick or wooden skewer to allow trapped steam to escape, preventing the interior from becoming dense or gummy.
VKB: Piercing releases steam instantly while keeping the outer crust smooth and intact.
Before moving to the next step:
Ensure every bun is pierced right away to maintain the airy structure.
Phase 6: Assembly and Serving – 10 min
Appliances: Stove
6. Melt 0.50 cup of unsalted butter for topping in a small pan. Place 2 hot steamed buns onto each serving plate, generously drizzle with melted butter, and dust liberally with 0.33 cup of powdered sugar and 0.33 cup of ground blue poppy seeds. Serve immediately while piping hot.
VKB: Butter should melt into the hot bun surface, creating a rich glaze alongside the sweet poppy seeds.

WAGUU Pro level
- Pro standard: Verified recipe with precise ratios and visual checkpoints.
- Tip 1: Use high-protein bread flour to provide strong gluten structure capable of trapping steam without bursting.
- Tip 2: Ensure the steamer basket is thoroughly greased or lined with parchment paper to prevent sticking.
- Tip 3: Keep the steaming water at a vigorous boil to maintain consistent steam temperature throughout cooking.
- Tip 4: Pierce the buns immediately upon removal from the steamer to prevent internal condensation from deflating the crumb.
Scientific background
Steaming operates through moist heat transfer at 212 °F, which gelatinizes starches rapidly and coagulates proteins without drying out the exterior crust. Unlike baking, steam cooking prevents Maillard browning reactions on the surface, resulting in a pale, uniform, and velvety exterior while maintaining an exceptionally moist interior crumb.
Fine Dining – Professional techniques
- Plate composition: Serve two warm buns dusted symmetrically with contrasting black poppy seeds and white powdered sugar.
- Texture contrasts: Combine pillowy soft steamed crumb with a rich molten fruit center and crunchy poppy seed coating.
- Temperature contrast: Contrast piping hot steamed buns with cold, fresh cultured butter melted directly on top.
- Aromatic garnishes: Finish with freshly grated lemon zest over the melted butter for an elevated citrus aroma.
Sensory radar
- Appearance: Uniformly rounded white buns dusted with dark poppy seeds and powdered sugar.
- Aroma: Sweet yeast fragrance mingled with nutty poppy seeds and rich butter.

FAQ
Why did my steamed buns collapse after cooking?
Collapsing usually occurs if the lid is opened too early during steaming, or if the buns were not pierced immediately upon removal to release internal steam pressure.
Can I freeze the steamed buns?
Yes, fully cooked and cooled buns freeze exceptionally well for up to 2 months. Reheat them directly in a steamer for 5 minutes before serving.
How do I prevent the dough from sticking to the steamer?
Generously brush the steamer insert with melted butter or oil, or place small parchment paper squares under each bun.
Can I use fresh yeast instead of active dry yeast?
Yes, use triple the amount of fresh yeast (approximately 1 oz) dissolved in the lukewarm milk with sugar.
WAGUU Petr advises: Cooking for 12 or more people?
12–16 people: Double all ingredient quantities and steam the buns in two separate batches using two steamer pots to ensure even cooking • 20+ people: Prepare the dough in two separate mixing batches to avoid overloading your mixer, and enlist a helper for efficient shaping and steaming.
Sides and serving
- Vanilla custard sauce – sweet warm custard poured over the buns (not included in the recipe)
- Fresh berries – seasonal tart berries for added freshness (not included in the recipe)
Serving: Serve piping hot on warmed dessert plates, drenched in melted butter and dusted generously with poppy seeds and powdered sugar.
Storage and reheating
Fridge: 2 days • Freezer: 2 months • Reheating: Steam for 5 minutes over boiling water until thoroughly warmed through.

Common mistakes
- Opening the steamer too early – Lifting the lid during the first 15 minutes lets cold air in, causing the rising yeast buns to deflate permanently.
- Failing to pierce hot buns – Forgetting to puncture the freshly steamed buns traps steam inside, leading to a dense, gummy interior texture.
- Under-kneading the dough – Insufficient gluten development prevents the dough from trapping gas properly, resulting in heavy, compact buns.
- Water touching the buns – Allowing boiling water to touch the buns directly makes them soggy instead of fluffy and dry-steamed.
