Use apples to ripen or heat.

1. In winter, the durian shell turns green, with almost no cracks at the end. If it smells faint, you can put it with the apples for three days, so that the hard skin can peel off if the ends are slightly cracked.

2. Place the entire durian shell on the gas stove and turn the durian frequently to evenly heat it, and it will slowly crack. However, don't bake the durian for too long. If the shell cracks completely, the durian meat may have a burnt taste and affect the taste.
