Ingredients

For the Asado Filling

  • 1 tablespoon canola oil
  • 1 small onion, peeled and chopped
  • 2 cloves garlic, peeled and minced
  • 1 pound pork butt or shoulder, cut into large chunks
  • 2 cups water
  • cup soy sauce
  • 2 tablespoons oyster sauce
  • 3 tablespoons sugar
  • 2 star anise
  • 1 tablespoon cornstarch

For the Siopao Dough

  • 260 ml warm milk (105 to 115 F)
  • 2 teaspoons dry instant yeast
  • 2 tablespoons sugar
  • ½ teaspoon salt
  • 500 grams all-purpose flour
  • 2 teaspoons baking powder
  • 100 grams sugar
  • 2 tablespoons vegetable oil
  • lime

Instructions

For the Siopao Filling

  • In a pot over medium heat, heat oil. Add onions and garlic and cook until softened. 
  • Add pork and cook, turning as needed, until lightly browned.
  • Add 2 cups of the water, soy sauce, oyster sauce, sugar, and star anise. Stir until well-dispersed. Bring to a boil, skimming scum that may float on top.
  • Lower heat, cover, and continue to cook for about 1 hour or until meat is fork-tender. Add more water in half cup increments as needed to maintain 1 1 /2 cups liquid.
  • With a slotted spoon, remove pork from the pot and let cool to touch. Using two forks, shred meat.
  • Remove about 1 cup of the braising liquid and set aside. Return shredded meat to pot and bring to a boil.
  • In a bowl, combine cornstarch and bout ¼ cup water. Stir until smooth and cornstarch is dissolved. Add half of the cornstarch slurry to the pot of meat and stir to distribute. Continue to cook for about 1 to 2 minutes or until thickened. Remove from pan and allow to cool.
  • In a saucepan over medium heat, combine the reserved 1 cup braising liquid and the remaining half of the cornstarch slurry. Bring to a boil, stirring regularly, for about 2 to 3 minutes or until thickened. This well be the siopao sauce.

For the Siopao Dough

  • In a bowl, combine milk, yeast, the 2 tablespoons sugar, and salt. Stir well until dissolved. Let stand for about 5 to 10 minutes or until the mixture is foamy.
  • In a large bowl, combine flour, the 100 grams sugar, baking powder, and vegetable oil. Mix well. Add a few drops of lime juice into the flour mixture.
  • Add yeast mixture to the flour mixture. Mix together until it forms a dough. Continue to mix and knead until the dough is smooth and no longer sticky.
  • Cover with a clean kitchen towel and allow to rise in a warm place for about 2 hours or until double in size.
  • Remove the dough from the bowl, place on a clean work surface, and form into a long log. 
  • With a knife, cut the dough into 10 equal size pieces and then form each piece into smaller balls. Cover the dough with a clean kitchen towel and allow to rise for about 30 minutes.

To assemble Siopao Buns

  • On a clean working surface, place one piece of dough, and with a rolling pin, roll out into about 4 to 5-inch diameter, making sure to get edges thinner than the center.
  • Place about a tablespoon of the meat filling in the center.
  • Gather the edges of the dough, pleat around the filling, and twist to fully secure. Place bun on a piece of parchment or wax paper. Repeat with remaining dough and filling.
  • Arrange prepared buns in a single layer on a flat baking sheet, cover with a kitchen towel, and allow to rise again for another 10 minutes.
  • In a steamer, place buns in a single layer, an inch-apart. Add about 2 tablespoons of vinegar to the steaming water (for whiter buns). 
  • Steam buns on low heat for about 15 to 20 minutes. Keep the lid on for about 3 to 5 minutes to prevent the buns from deflating.
  • Remove from steamer and serve with the asado sauce.
