1. Prepare 500g of flour, pour 20g of edible oil, mix the flour with hot water and cold water, knead it into smooth dough, and seal it for half an hour.

2. Ventilate the dough, put it into a uniform size agent, shape the agent, roll it into a cake blank, pour a little oil on the cake, spread it evenly on both sides, roll it into a thin cake crust with a rolling pin, and fold it in half layer by layer.

3. Stretch the crust, roll it up from the outside to the inside, press it into biscuits, and continue to roll it into a round crust, so that the biscuits are ready.

4. We will keep it with plastic wrap after it is done, and a layer of cake blanks will be kept in the refrigerator with plastic wrap. Take it out when you want to eat, which is healthy and hygienic.

5. The cake is crisp and delicious.
