1. Put 1 teaspoon of alkali flour and 1 gram of salt in the flour (1 teaspoon of salty flour is enough, do not do more, avoid foaming) and then put an egg (which plays a role in promoting the flow of water). Mix well, add 250 grams of water and flour, knead well, and knead it. During this period, knead several times to form a smooth dough
2. Soak the soybeans and green beans 6 hours in advance (if there is no time to soak them in boiling water for 1 hour), then add 1 large material, 10 Chinese prickly ash and 1 g salt to boil, then shred cucumber and XinLiMei, dice celery and blanch bean sprouts
3. Diced streaky pork (the old Beijing fried sauce is fried with diced meat, without meat stuffing); mix the yellow sauce with water (not too thin)
4. Pour the oil in the pan (more oil, otherwise it will not smell), stir the diced meat after the oil is hot, and then add the scallion and ginger and a large material, cook 1 teaspoon cooking wine to improve the aroma, and then stir a few times to get the oil; Boil the sauce, turn it to a high heat, and then turn to a low heat to boil it slowly (when boiling, it should have small bubbles. Remember, keep stirring the bottom with a shovel, or it will stick to the pot). In the meantime, put sugar (to neutralize the salty taste and also play a heavy role). Boil it for about 10 minutes. Put it in a bowl, and the oil will slowly float up to seal the sauce
5. Put the dough on the chopping board and roll it into a thin cake (the thickness should be controlled according to your own preference)
6. Fold the pancakes and cut them into strips, then cook them in boiling water. Add all vegetables and fried sauce to enjoy
