If you want to make your own sour noodle soup, you need to prepare some materials first, including 500g of flour, 300g of water, proper amount of edible salt, scallion, edible oil, soy sauce, aged vinegar, laver, shrimp skin, chicken essence, coriander, edible salt and white pepper.

First add a proper amount of water to the flour, then add a spoonful of edible salt, put it in the pot and rub it directly by hand. The kneading time should be about three minutes. After kneading the dough, we directly roll the dough into a rectangle with a rolling pin, then cover it with plastic wrap and let it stand for 20 minutes. After 20 minutes, we cut all the dough into uniform strips, then put clean cooking oil on each strip and oil on both sides. Then we cover all the greased noodles with plastic wrap and put them aside for more than an hour, the longer the better.

Chop all the green onions prepared in advance, put a proper amount of cooking oil in the pot, put the chopped green onion in the pot after the oil is hot, and take out the chopped green onion when it is fried to golden brown. Prepare a bowl and put all kinds of spices in it. You can add or delete some condiments according to your personal taste, and then put a spoonful of chopped green onion oil in the bowl.

Next, we will roll out all the noodles and press them in the middle of the dough with chopsticks. After seeing the noodles spread out, we can divide the dough into two pieces, so that the noodles are ready. Add water to the pot and bring it to a boil. After boiling, put the noodles directly into the pot and cook them. It will take about 3-5 minutes to fish out. Wash the noodles out with cold water, drain the water, put them directly into the freshly seasoned bowl, pour hot oil on them, and you can eat them directly. In fact, Shaanxi people prefer sour soup Lamian Noodles. When cooking this delicious food, the most important thing is to master the ratio of water to flour.
