The egg custard steamed in the microwave oven will explode because of the water wrapped in the solidified egg liquid, and the water vapor generated when boiling spreads the solidified egg liquid, thus causing an explosion. When using the microwave oven to steam egg custard, the power of the microwave oven can be appropriately reduced, so that the egg custard can be heated slowly from the inside out.

Besides, cooking eggs in the microwave oven will also explode, because the eggs are heated from the inside out, and the heat generated by the eggs themselves will not be released when they touch the closed eggshell, which will lead to explosion.

precautions for explosion prevention of microwave oven

1. When the liquid is heated by microwave, the water will not flow, but the temperature will rise, which may exceed the boiling point and there is no sign of boiling. But if there is a slight movement, such as opening the door of the microwave oven, the water inside will boil violently, causing burns.

2. Some fruits contain salt ions, which will generate a strong electric field under the vibration of the microwave oven, such as grapes, blueberries, cherry tomatoes, etc. If they are put into the microwave oven, they are likely to explode.

3. Most plastics should not be heated by microwave oven. The only plastic that can be put into microwave oven is polypropylene. If it is not clear, to be on the safe side, don't heat the plastic container unless it is marked as heatable.
