Siopao Dough
3 cups all-purpose flour
⅓ cup sugar
½ tablespoon instant yeast
½ tablespoon baking powder double-acting
⅔ cup lukewarm milk
⅓ cup lukewarm water
3 tablespoon shortening
1 tsp vinegar to make dough white

Filling
250 grams ground pork
1 medium onion chopped finely
1 small egg
1 teaspoon garlic powder or 1-2 cloves garlic minced
1 tablespoon flour
½ teaspoon ground pepper1 tablespoon sesame oil* only if available
2 tablespoon oyster sauce* only if available
salt if needed

How to make the Dough

1. Combine the flour, sugar, yeast, and baking powder in a large bowl. Pour in the milk and water and vinegar and mix a few times just to moisten the dry ingredients. Cut in the shortening and mix until a dough forms.
2. Tip the dough onto a flat surface and knead until smooth and elastic. This usually takes about 10–12 minutes by hand or 8–10 minutes with a mixer.
3. Let the dough rest for 20–30 minutes, or until it has risen to almost double its original size. (Meanwhile, prepare the filling.)
4. Turn the dough onto a lightly floured surface and roll it into a log. Divide it into two portions. Return one half to the bowl and place it in the fridge to slow down the rising process.
5. Divide the other half into five equal parts. Fold each piece toward its center several times until it is no longer puffy and becomes smooth. Then form each piece into a ball.

How to prepare the filling

• Add all the ingredients for the bola-bola (meatball) in a bowl. Mix until well combined.
• Cover with plastic wrap and let it rest for a few minutes or until the dough is ready.
