Fire, about 4-6 minutes. It takes 5 to 6 minutes to heat chestnuts with shells in the microwave oven. Cut out a small chestnut mouth with scissors of 0.2mm~0.3mm and put it in the tray of microwave oven. Put the chestnuts with a cross knife into a high-temperature resistant container and put some water in it.

Put the chestnuts in the microwave oven, turn on the fire for 2.5 minutes, take them out and shake them a few times. If you want to fry chestnuts with sugar, you can add cooking oil and sugar at this time, then shake them well and put them in the microwave oven for 2 minutes, depending on the size of chestnuts. Generally, it will be cooked in about one * * * four minutes, and the big chestnuts may take 5-6 minutes.

Note: chestnuts must be roasted before opening to avoid explosion caused by a large amount of water vapor accumulation.

I'm afraid it will explode when I open my mouth. I can soak chestnuts in water for a while and then heat them in the microwave oven, which can increase the moisture in chestnuts and prevent them from exploding.

Chestnuts can't be heated for a long time, 3 to 5 minutes is enough. Heating for a long time will evaporate the water of chestnut and make chestnut very dry.
