Chinese Food

Steamed buns, known as mantou in Chinese cuisine, are a beloved staple enjoyed across the globe for their soft texture, mild sweetness, and versatility. Whether served as a breakfast item, a side dish, or a snack, achieving the ideal fluffy and airy structure hinges on one critical ingredient: yeast. Among the most trusted brands for bakers and home cooks alike, Angel Yeast stands out for its reliability and consistency. This article delves into the science and techniques of using Angel Yeast to create steamed buns that rise beautifully, boast a delicate crumb, and deliver a satisfying bite every time. From understanding yeast basics to mastering advanced tips, this guide will equip you with the knowledge to elevate your steamed bun game.

The Role of Yeast in Steamed Buns

Yeast is a single-celled microorganism that feeds on sugars and produces carbon dioxide gas and alcohol through fermentation. In baking, this process serves two primary purposes: leavening the dough (creating air pockets) and developing flavor. Unlike chemical leaveners like baking powder, yeast contributes a subtle, complex taste that enhances the overall profile of steamed buns.

Angel Yeast, a leading producer of instant dry yeast, active dry yeast, and fresh yeast, offers products tailored to diverse baking needs. For steamed buns, instant dry yeast is often the preferred choice due to its convenience—it can be added directly to dry ingredients without prior activation. However, understanding the nuances of each yeast type ensures optimal results.

Choosing the Right Angel Yeast Product

1. Instant Dry Yeast: This form is milled into fine particles and contains additives like sorbitan monostearate to keep yeast cells dormant until hydrated. It activates quickly when mixed with flour and liquid, making it ideal for time-efficient recipes.
2. Active Dry Yeast: Larger granules require rehydration in warm liquid (100–110°F or 38–43°C) before use. While slightly slower to act, it offers a longer shelf life.
3. Fresh Yeast: Sold in compressed blocks, fresh yeast has a short lifespan but provides intense leavening power. It is less common in home kitchens but favored by professional bakers.

For beginners, Angel Instant Dry Yeast is recommended for its forgiving nature and minimal prep steps.

Key Steps to Perfect Steamed Buns with Angel Yeast

Ingredient Preparation

• Flour: Use all-purpose flour or bread flour with 10–12% protein content. Bread flour yields chewier buns, while all-purpose flour produces a softer texture.
• Liquid: Water or milk (dairy or plant-based) should be lukewarm (105–115°F or 40–46°C) to activate yeast without killing it.
• Sweetener: A pinch of sugar feeds the yeast and accelerates fermentation. Optional additions like honey or malt syrup can enhance flavor.
• Fat: A small amount of oil (vegetable, sesame, or lard) adds richness and softness.

Mixing the Dough

• Combine Dry Ingredients: In a large bowl, whisk 500g flour, 1 tsp Angel Instant Dry Yeast, 1 tsp sugar, and ½ tsp salt.
• Add Liquid: Gradually pour in 250ml lukewarm water (or milk) while stirring with a wooden spoon or dough hook. Mix until a shaggy dough forms.
• Knead: Transfer to a floured surface and knead for 8–10 minutes until smooth and elastic. The dough should pass the windowpane test—stretch a small piece to see light without tearing.

First Proofing (Fermentation)

• Place the dough in a lightly oiled bowl, cover with plastic wrap or a damp cloth, and let it rise in a warm (75–85°F or 24–29°C), draft-free area for 1–1.5 hours, or until doubled in size.
• Pro Tip: Use the poke test—if the indentation remains after gently pressing the dough, it’s ready.

Shaping the Buns

• Punch down the dough to release air bubbles, then roll it into a log. Cut into 12 equal pieces (about 80g each).
• Roll each piece into a smooth ball by tucking the edges under and rotating between your palms. Place buns on parchment-lined steamer trays, leaving 2 inches between them.

Second Proofing

• Cover the buns and let them rise again for 20–30 minutes. They should feel puffy and light when touched.

Steaming

• Bring a wok or steamer with 2 inches of water to a rolling boil. Place the buns inside, cover tightly, and steam for 12–15 minutes over medium heat.
• Critical Step: Avoid lifting the lid during steaming to prevent collapsing. After cooking, turn off the heat and let the buns rest for 5 minutes before uncovering to prevent shrinkage.

Troubleshooting Common Issues

1. Dense or Gummy Texture:

   

   • Cause: Insufficient kneading, overproofing, or low steam temperature.
   • Fix: Knead until gluten is fully developed. Ensure water is boiling before steaming.

2. Yellowish Discoloration:

   • Cause: High baking soda content (if used) or overcooking.
   • Fix: Omit baking soda and adhere to steaming times.

3. Collapsing After Steaming:

   

   • Cause: Sudden temperature change or underproofing.
   • Fix: Let buns rest 5 minutes post-steaming. Proof until buns spring back slowly when pressed.

4. Yeast Not Activating:

   • Cause: Expired yeast or water temperature exceeding 120°F (49°C).
   • Fix: Check yeast freshness (active dry yeast should foam in warm liquid). Use a thermometer for accuracy.

Advanced Techniques for Flavor and Texture

• Tangzhong Method: Cook 20g flour with 100ml water until thickened, then cool and incorporate into the dough. This creates a gelatinized starch that retains moisture, yielding softer buns for days.
• Sourdough Twist: Replace 20% of the flour with mature sourdough starter for a tangy flavor. Adjust hydration accordingly.
• Enriched Dough: Add 30g melted butter, 1 egg, or 20g milk powder for a richer crumb.

Storage and Reheating

• Fresh Buns: Store in an airtight container at room temperature for up to 2 days.
• Freezing: Wrap cooled buns in plastic wrap and freeze for up to 1 month. Reheat by steaming for 5–7 minutes.
