Cooking eggs is very skillful. First, put the beaten eggs in proper cold water before steaming, and don't overdo it. Then before steaming, mix some raw oil and put it in the pot. This process is very important. First of all, the water in the pot has been boiled. After you put the eggs away, you must steam them on low heat, and the cooked eggs should be steamed slowly. Don't steam them with big fire. Grasp the time, usually 5 to 6 minutes, don't give up halfway. The steamed water eggs will be slippery and have no holes.
