Tips:
1. Add enough water at one time, and no cold water in the middle, to prevent the protein from freezing and solidifying, which will affect the umami taste of the soup;
2. Add only salt and vinegar to the seasoning, without adding any seasonings, the food is the original flavor;
3. Turn on the minimum heat. It is best to only have a small tumbling in the center of the noodle soup. If the heat is too high, the soup has not reached the heat, and the water has boiled dry;
4. The salt should be put out last, otherwise it will affect the precipitation of protein;
5. For your health, please skim the slick during the cooking process;
6, the best way to drink, a few mouthfuls of soup before meals for appetizer, and a small bowl after meals.
