Required materials: 400g flour, 4g yeast powder, 2 10ml warm water, appropriate amount of salt and pepper (sesame salt and pepper are also acceptable), and appropriate amount of vegetable oil.

Exercise:

1. First, knead flour, yeast powder and water into a smooth dough and let it stand for fermentation (about one hour).

2. Take out the dough and knead it, adding some flour while kneading, about 70 ~ 80 grams.

3. Try to knead the dough into a cuboid and cover it with plastic wrap to relax for a while. Note: when covering the plastic wrap, sprinkle some dry flour on the dough. Don't press the plastic wrap tightly on the dough surface, otherwise the loose dough will easily stick to the plastic wrap.

4. Roll the dough into rectangular slices.

5. Spread a layer of oil evenly on the dough, sprinkle with salt and pepper, and then sprinkle with some dry flour. Then fold it as shown.

6. After folding, cut it in half from the middle.

7. Try to pinch the incision tightly, let it stand for 5 minutes, then flatten it and roll it into a cake. Put cold water on the pan, and it will burn after 10 ~ 15 minutes. Turn off the fire after 15 minutes, and stew for 5 minutes.

8. After steaming, cut into pieces.
