2. It is best not to eat leek scrambled eggs overnight

But it is best not to eat leek scrambled eggs overnight. Leek contains volatile essential oil, protein, sulfide, fat, carrot, sugar, vitamin B, C and other nutrients, which is very beneficial to human health. However, leek contains a lot of nitrate, which can be converted into nitrite if it is stored for too long after frying, and people will be poisoned after eating it. Therefore, fried leek scrambled eggs cannot be eaten overnight; In addition, the storage time of raw leeks should not be too long.

3. Steamed eggs can be eaten overnight

Actually, eggs can be cooked and reheated the next day before eating. However, half-cooked eggs can't be eaten after overnight! If eggs are not fully cooked, they are easy to breed bacteria under improper storage, such as gastrointestinal discomfort and flatulence.

At the same time, some people think that the longer the eggs are cooked, the better, which is also wrong. Because the eggs are cooked for too long, ferrous ions in the yolk combine with sulfur ions in the protein to form insoluble ferrous sulfide, which is difficult to be absorbed. When fried eggs are over-aged, the edges will be scorched, and the high molecular weight protein contained in egg white will become low molecular weight amino acids, which can often form chemicals harmful to human health at high temperature.

what should you pay attention to when cooking eggs

1. Break eggs with the edge of the bowl or stove: breaking eggs with a clean flat surface (not the edge of the bowl) can prevent broken eggshells from falling into the bowl, causing pollution, and at the same time avoid wasting the egg liquid brought out by fishing broken eggshells.

2. Boil eggs in boiling water: Try not to boil eggs in boiling water, otherwise it will not only cause the eggshell to break and the egg liquid to flow out, but also easily burn your fingers. The correct way is to put the eggs in the pot with cold water, raise the temperature slowly, boil for 3 minutes after boiling, and soak for 5 minutes after stopping the fire. The egg cooked in this way is tender and the yolk is not old.

3. Shell the mature eggs after natural cooling: This shelling is not only time-consuming and laborious, but also easy to leave the protein on the eggshell, resulting in waste. The time-saving and labor-saving way is to put the boiled eggs into cold water immediately after taking them out, and peel them as soon as possible when they don't feel hot.

4. Stir-fry the eggs over high fire: Stir-fry the eggs over high fire easily, and make them hard to taste. Scrambled eggs are the most
