1. If the tripe is cooked in a pressure cooker, it will usually be cooked in 30 minutes; if it is cooked with slow fire, it will take 2-3 hours. The time is different under different circumstances. If the belly is thin or the firepower is relatively large, the time for stewing the belly will be shorter.

2. If the tripe is to be boiled, put baking soda and baking powder. These substances will produce bubbles, which will expand the tissue of meat, make water enter it and rot quickly.

3, putting tea leaves has the same effect, and it can also make the meat taste more delicious. Put half a bag of baking powder and add tea bags. Tripe is about 1kg, and chopsticks can be easily inserted after cooking for about half an hour.
