I used to have your curious idea ~ I didn't know it until I had a chance to witness the production process. So that's it: just use cold water and thin flour, put a layer of oil on it, and then leave it for about 40 minutes to an hour. When you use it, you can directly crush it into the size you need, then spread it flat on the palm of your hand, then put it flat in the pot with bread, and you can fry it. This process requires putting some oil in your hand. I don't know if you understand. I wish you a delicious pie as soon as possible! ! ! !
