    For steaming

    Instructions

    • Marinate the pork. Mix all the dry rub marinate and then coat the pork generously. Marinate overnight for the best flavour.
    • Make the Asado Sauce. Add all the Asado sauce ingredients in a saucepan and mix until blended. Simmer for 10 to 15 minutes to infuse the aromatic. Use a strainer to remove the aromatic. Add the slurry and mix until the Asado sauce thickened. Cover and set aside.
      How to make asado sauce
    • Slow-cook or braise the Pork Asado. In an Instant Pot, drizzle a tablespoon of canola oil. Sear the pork on each side for a few minutes until it has a brown crust. Add a couple of tablespoons of water and the juice from the marinade. Then add about half a cup of Asado sauce. Slow-cook for 6.5 hours or braise the marinated pork cubed with sauteed onion and garlic for 2 hours.
    • Make the siopao dough. Mix the active dry yeast, warm water and sugar in a bowl of a stand mixer. Set aside for 5 minutes or until foamy. Mix half of the flour, cornstarch, baking powder and salt in a bowl to ensure all the dry ingredients will blend well before adding to the wet ingredients.
      Add the milk and the dry ingredients to the yeast mixture. With the dough attachment, knead and alternately add the shortening and the rest of the flour. Knead for about 8 minutes. Do a windowpane test to ensure the dough is kneaded enough and ready to rise. Grease the bowl with cooking oil and the dough. Cover and let it rise in a warm place for an hour or two until it doubles in size.
    • Divide the siopao dough. Deflate the dough and divide it into 12 weighing about 105 grams to 110 grams each for large siopao. Or 24 weighing about 55 grams each dough. Form each dough into a ball.
    • Filling the siopao dough. Flatten the dough and make the edges a bit thinner with the rolling pin. Add a scoop of the pork Asado in the middle of the dough. Make about 6 to 8 pleats, pinching the dough as you go while pushing the filling inside until gathered in the middle. Pinch hard to ensure it will not open when steaming.
    • Place each filled siopao on a parchment paper. Cover and proof for 20 to 30 minutes.
    • Steam the Siopao. Add water to the steamer and bring to a boil. Add vinegar for a whiter dough. However, it also depends on the flour you gonna use.  Place the proof-filled dough in the steamer about 3 to 4 inches apart. Steam the large siopao for about 20 minutes and steam the small siopao for 15 to 18 minutes. Transfer the Asado sauce to a squeeze bottle if available.
    • Serve the siopao hot and serve with the Asado sauce in a squeeze bottle or soy dish.
