1. 400 grams of flour, 235 grams of warm water, 4 grams of yeast, 10 grams of sugar, and appropriate amount of vegetable oil. Pour the flour, warm water, yeast, and sugar into a basin, stir, knead into a dough, and ferment until it is 1.5 to 2 times in size.

2. Knead the risen dough, deflate it, and divide it into 12 small dough pieces, each approximately (50-53 grams).

3. Roll the small dough into a round pancake, not too thin, apply a layer of vegetable oil on top, and wrap it into a bun shape.

4. Turn the "hollow" bun over and roll it into a small cake. If there is air inside, be careful not to break it. You can also press it gently with your hands into a round cake shape.

5. Heat the pan (or electric baking pan) without adding oil. Put in the cake base, shape it on one side and then turn it over. Bake until both sides of the cake are golden and swollen. Be careful not to bake for too long. Too long or it will become hard.

6. Cut the prepared pie crust with scissors.

7. Add your favorite fillings: minced pork belly, diced green pepper, and chopped coriander.
