Step1:First add boiling water to the flour. Stir with chopsticks. Then add cold water. Stir again. Then mix with hands and flour until smooth. (dough is wet and difficult to operate. It can be greased and dropped by hand) cover it with a cover and wake up for 30 minutes.
Step2:When you wake up, make the pastry. Pour a proper amount of heated oil into the bowl of flour. You will hear the crackling sound. Use chopsticks to stir evenly. Cut the onion. Cut more. Then divide the dough into 4 parts. Roll it round. Roll it thin as much as possible. Put on the pastry. Sprinkle salt and white pepper. Sprinkle more onion. Roll it up. Then dish it up (or fold it like a fan and dish it up or cut it up) Fold nine layers after four strokes).
Step3:Roll out the first one after all four pieces of cake skins are rolled. Roll thin as much as possible. Open fire. Heat the pan. Add less oil. Put in the cake skins. (each pan is just 28 in size). Turn it over in about 30 seconds. Turn it over three times and nine times. It's about 3 minutes. It's golden on both sides. Add a little oil. Roll out the second one.
