Generally, it takes about 3-4 minutes to steam egg custard in microwave oven. It is recommended not to steam all the time with big fire. You can try steaming on high fire for 2 minutes, then turn to 80 degrees and steam on medium fire 1 minute. Remember not to tighten the lid too tightly when steaming, so that the steamed omelet tastes better.

Generally, the ratio of water to eggs is about 1:3. If there are 1 egg, put 3 times the water of the egg liquid.

1, avoid adding raw water and hot water. Add raw water because there is air in tap water. When water is boiled, air will be discharged, and small beehives will appear in custard, which will affect the quality of custard, lack tenderness and destroy its nutrients. It is not advisable to use hot boiled water, otherwise the boiled water will heat the egg liquid before steaming, which will destroy the nutrition and even steam the egg custard. It is best to steam the custard with cold boiled water, which will avoid the loss of nutrition and make the custard smooth, tender and delicious.

2. Avoid stirring the egg liquid. Stir the egg liquid vigorously or for a long time before steaming will make the egg liquid foam, and the egg liquid will not dissolve into one when steaming after stirring. It is best to beat the egg mixture evenly, add warm water and then break it up slightly and stir.

3. Avoid adding condiments before steaming. If seasoning is added to the custard before steaming, protein will be denatured and its nutrition will be damaged, and the steamed custard will not be fresh and tender. The seasoning method should be: after steaming, cut the custard several times with a knife and add a little cooked soy sauce or salt water, chopped green onion, sesame oil and so on. The custard made in this way is delicious, tender and nutritious.

4. The steaming time should not be too long and the steam should not be too large. Because the egg liquid is rich in protein, it will gradually solidify into blocks when heated to about 85℃. If steamed for too long, the custard will harden and the protein will be destroyed. Too much steam will make the custard honeycomb and reduce the umami flavor.

The best way to steam the custard is to deflate, that is, when steaming the custard, don't cover it tightly, leave a gap and run while steaming. The best time to steam eggs is when they are ripe and tender.
