Durian can be hardened by ripening durian meat, keeping durian in a warm environment for a few days, putting hard durian meat in a microwave oven, freezing raw durian in a refrigerator and softening it with ethylene gas.

1. Ripening durian meat

As we all know, persimmons can be ripened, so can durian. Put durian and those ripe fruits in a closed container for a few days, and durian will become ripe and soft, and its taste will be better.

2. Keep durian in a warm environment for a few days

If you can't find the ripe fruit, you can put durian in a box and seal it, or put it directly in a warmer place, such as a window sill. After a few days, durian may become ripe and soft.

3. Put the hard durian meat in the microwave oven.

The hard durian meat can be wrapped in plastic wrap and cooked in the microwave oven. The hard durian meat will immediately become soft. Although the taste is not as good as that of naturally cooked durian, you can manage to eat it.

4. Freeze the raw durian in the refrigerator

If it is a durian that has not been opened, you can keep the whole durian fresh in the refrigerator first, and it will mature in about two or three days.

5. Ethylene gas

Or put durian in a bag and then add ethylene gas into the bag, which can also ripen durian and make it taste better.
