The steps of sweet and sour cold noodles:
1. Cook the eggs, slice or cut them in half, and cut all the materials to prepare. Use prepared boiled water or direct drinking water as the soup base. Add two spoonfuls of sugar first, then add shredded ginger.
2. Scoop out lemon juice and add it to the soup base, then put it in the refrigerator for later use. When cooking noodles, be sure to use cold water to cook the pot. It is best to soak noodles in cold water 10 minutes before cooking.
3. After the noodles are cooked thoroughly, you should go through Leng Jiang for three times, wash the cooked noodle soup, and finally put the cooked noodles into the ice soup, and arrange other ingredients neatly and beautifully on the noodles.
