Steps: 1. Put the yeast powder in a small bowl, add a little white sugar, and take100g from190g warm water and pour it in. 2. Stir well, let it stand for 5 minutes and 3.5 minutes, then pour the yeast water into the flour, start to mix the flour, and continue to add the rest of the water, and do not add it at once. According to the different water absorption of flour, it can be slightly adjusted! Knead the dough into a three-light (face light, basin light and hand light) dough, and seal it for fermentation. 4. About 1 hour, the dough will be twice as big, and it will not shrink when pressed with your fingers. 5. Take the dough out and put it on the chopping board to knead it smoothly, so that the flour can be sprinkled to prevent sticking! Relax after kneading 10 minutes 6. Divide the relaxed dough into two parts, take one part and roll the dough into a large piece with a rolling pin, not too thin! Sprinkle salt, corn oil, and salt and pepper evenly. 7. Then roll it up, roll it into a long roll, and cut it into three parts evenly with a knife. 8. Squeeze a small cut at both ends by hand and flatten it to form a cake embryo. 9. Roll a cake embryo into a circle 10. Brush it with a thin layer of oil after the pan is heated, and put it on a low heat. Fry the other side until golden 12. Take out the pan and eat a piece while it's hot. It's crispy outside and tender inside 13. Refrigerate what you can't eat. Fry an egg for breakfast and put some pieces of meat in it. It's also very good.
