Directions

Make the Filling

1. Season the ground beef with soy sauce, oyster sauce, dark soy sauce, 1 minced garlic, ginger, five spice powder, white pepper, Sichuan peppercorn powder, and sesame oil. Then stir in 1/3 cup of beef stock in one direction to develop the texture. Set it aside.
2. Bring a pot of water to a boil and turn off the heat. Use the hot water to soak the sweet potato starch noodles for about 4-5 minutes. You can also use mung bean noodles but you have to soak it for just 1 minute because mung bean noodles are so thin.
3. Take the noodles out and shake off the excess water. Roughly dice the noodles.
4. Thoroughly combine the noodles, diced scallion, and cilantro with the ground beef, and the filling is done. Set it in the fridge.
5. Make the Wrapper
6. Combine 1/4 tsp of salt, 1/2 tsp of instant yeast, and 1 tbsp of oil with 160 grams of room-temperature water and Stir this well.
7. Pour the mixture into 300 grams of all-purpose flour in batches. Stir it with a pair of chopsticks at the same time.
8. Gather all the flour together until a rough dough forms. Let it rest for about 10 minutes to relax the gluten.
9. Knead the dough for 5 minutes until smooth and elastic. Let it rest for another 10 minutes.
10. Poke a hole in the middle to create a donut. Enlarge the hole. Cut it open, and you will have a long log. Divide the log into 12 even pieces. Each one should be around 38 grams.
11. Dust some flour, so they don’t stick to each other. Cover them to prevent them from drying out.

Make the Wrapper

1. Dust one piece of dough with some flour to prevent stickiness. Next, use a rolling pin to roll it flat. Once you get it to 3 inches in diameter, lift the sheet and roll the edge to make it thinner. That way, you can have a wrapper with a thicker middle and a thinner edge. The size of wrapper should be about 4.5 inches in diameter.
2. Put about 3 tbsp of filling on the wrapper. Pack it tight. The right hand lifts and pinch the edge of the wrapper. The left hand helps to push to fold the pleat. Just do that all the way around. When you get to the end, twist and pinch to close the bun.
3. Set the bun aside and continue to wrap the rest. Let them proof for 50 minutes to 1 hour.
4. Add cooking oil to the frying pan and turn the heat to medium. Place the buns in the frying pan, leaving some space between them to form a crust.
5. Mix 2.5 tsp of cornstarch and 1/3 cup of water in a separate container and pour the cornstarch mixture into the frying pan.
6. Put on the lid and let the buns cook for about 8 minutes while moving the pan to arrange the heat. Leave a small gap for steam to escape if the lid seals well.
7. Check if all the water has evaporated and the cornstarch has formed a crust at the bottom of the pan.
8. Gently shake the pan to see if the buns release themselves. If not, wait for 10-20 more seconds and try again.
9. As soon as the buns release themselves, turn off the heat. Note: The cornstarch crust may not be golden brown, but the bottom of the buns is perfectly done. Don't wait until the crust turns golden brown or else the buns will be burned.
