Ingredients
  

Salted Egg Yolk Filling

  • 3 salted egg yolks, steamed for 10 minutes
  • 30 grams cornstarch
  • 30 grams milk powder
  • 60-70 grams unsalted butter, melted use more if needed
  • 40 grams granulated sugar
  • 10-20 ml whole milk use more if needed
  • pinch turmeric optional: for coloring

Bun Dough

  • 200 grams all-purpose flour
  • 2 grams baking powder
  • 2 grams instant yeast
  • 35 grams granulated sugar
  • 135 grams warm water

Instructions
 

Make Filling

  • After steaming the egg yolks, add egg yolks to a food processor and pulse for 10 seconds.
  • Add melted butter, cornstarch, milk powder, sugar and turmeric, then pulse again for 10 seconds.
  • Add milk and pulse until you get a paste-like consistency.
  • Add water to a pot and bring to boil, then place a heat-safe bowl over the pot (you have made a double-boiler) and transfer the filling to the bowl.
  • Start stirring the filling as the water heats up, melting the filling. Keep stirring until you get the consistency you desire. If the filling is too thick, add milk ¼ teaspoon at a time to make it runnier.
  • Remove from the heat and place it in the fridge to harden for 2 hours.
  • When the filling has hardened, shape into balls weighing 14-18 grams each, then put it back in the fridge while you assemble the bun dough.

Make Bun Dough

  • In a bowl, add flour, baking powder, instant yeast and sugar then mix.
  • Incrementally add the warm water to the mixture until the dough comes together.
  • Move the dough to a flat surface and knead for 8 minutes while folding the dough over itself.
  • Cut the dough into 10 pieces weighing about 35 grams each and shape into balls.

Assemble Liu Sha Bao

  • Take a dough ball and flatten it out with a rolling pin, rolling out the edges to keep the middle thick.
  • Add a filling ball to the center and wrap the dough around the filling, pinching it closed.
  • Place on a square piece of wax paper and set aside in a steamer basket.
  • When all the buns have been assembled, proof for 30-40 minutes.

Cooking Buns

  • Heat water in a big pot and bring to boil.
  • Place steamer basket on top of the pot and set the timer to 5 minutes.
  • After 5 minutes, remove the steamer without opening and place on counter to cool for 2 minutes.
  • Serve immediately
