When buying immature durian, wrap it in a newspaper at home, light the newspaper, wrap it in another newspaper after burning and put it in a warm place. You can smell the fragrance in a day or two, which proves that it is mature. When you want to eat, you can lift it and throw it on the ground, break it out and pry it open from the gap to eat. It is forbidden to drink alcohol within nine hours after meals. Boiling water with durian shells can reduce the calories of durian.

Durian has the function of ripening. If it is stored in a cool place, the ripe fruit will crack. At this time, you can take out the pulp, put it in a fresh-keeping bag and store it in the refrigerator. After being chilled, it will taste like ice cream. If the pulp turns sour, it means that durian has gone bad and can't be eaten any more. The unopened durian smells like grass when it is immature, while the mature durian exudes its inherent fragrance.
