Dry Compounding & Aeration
Whisk tapioca starch, rice flour, sugar, baking powder, yeast, and salt in a commercial bowl. Sift twice to guarantee absolute smoothness.
Warm Hydration & Fat Emulsion
Add warm water and melted coconut oil. Mix with dough hook on medium speed for 6 minutes until a smooth, non-sticky, pliable white dough coalesces.
Rolling & Lotus Leaf Folding
Scale into 60g portions. Roll into 10cm ovals (5mm thickness). Brush surface lightly with sesame oil or neutral oil. Fold in half over an oiled parchment paper square to form the classic clam-shell pouch.
Proofing Cabinet Cycle
Place on parchment paper squares inside a commercial proofing cabinet at 32\u00b0C (90\u00b0F) with 75% relative humidity for 22 minutes until light and puffy.
Commercial Steam Cabinet Cooking
Transfer into commercial combi-steam oven (100% steam at 100\u00b0C / 212\u00b0F) or tiered bamboo steamers over boiling water. Steam for 12 minutes. Turn off steam and let rest 3 minutes with door cracked before removing.
