Generally, when making soup, the onion (ginger) will be fried with oil first, and then water will be added, and there will be white foam in the water.

1. Wash the pot, add clean water (depending on the number of people who try to drink), add onion or ginger, add starch when the water boils (stir the starch with water at this time), and wait until the water is slightly thick (don't put too much starch). When the water is boiled again, pour the beaten eggs into the pot, stir slowly along the edge of the pot with a spoon, and add seasoning and starch after boiling.

2, tomato and egg soup: put a small amount of oil in the pot, after the oil is hot, add onion or ginger to stir fry, add chopped tomatoes to stir fry (at this time, use medium fire, the tomato will fry if the fire is too strong, and the fried tomato juice will also dry up), after the tomato juice is squeezed, add water to boil, and the step after boiling is to add starch, eggs, square seasoning and sesame oil.
