Molten Custard Buns流沙包

Molten Custard Buns, or Liu Sha Bao, are a beloved dim sum specialty featuring a soft, fluffy steamed bun exterior and a rich, creamy, and slightly salty-sweet custard filling that flows out when bitten into. The filling gets its unique flavor from salted duck egg yolks and a blend of milk and custard.

02Steps
  1. Steam the salted duck egg yolks until cooked, then mash them thoroughly.
  2. Melt the unsalted butter.
  3. Combine the mashed salted duck egg yolks, melted unsalted butter, powdered sugar, custard powder, milk powder, evaporated milk, and coconut cream. Mix well until smooth.
  4. Chill the filling in the refrigerator until firm, then divide into small balls of approx. 15-20g each.
  5. In a large bowl, combine the all-purpose flour, wheat starch, sugar, baking powder, and instant dry yeast.

  7. Cover the dough and let it rest in a warm place for about 30-60 minutes, or until it doubles in size.
