Theoretically, you can use a microwave oven to heat cold mangoes. However, it should be noted that heat will make mango soft and rotten, and because mango contains a lot of water, heat may cause it to crack or spray. If you want to make mangoes sweeter, you can let them stand at room temperature for a while and wait for them to ripen. If you want to make the mango warmer, it is recommended to put it in a heat-resistant container and heat it slightly in the microwave oven (for example, 15 seconds -30 seconds) before eating. Please pay attention to draw a simple cross shape on the surface of mango with a knife to avoid sudden bursting during heating.
