1, fat sausage is usually cooked in the right way for one hour. If cooked in a pressure cooker, it only takes 15 minutes. If it is not cooked well, it may be undercooked.

2. If you want to cook the pig's large intestine worse, you can soak it in water before cooking, soak it in warm water for 2 hours, and be sure to use cold water when cooking, so as to ensure better heating of the pig's large intestine. You can add a little edible alkali to the water, boil it with high fire, and then turn to low heat for 40 minutes. If you have broth at home, you can add a little, or add a little meat oil to make the fat sausage more crisp and rotten. Finally, turn to high heat and cook for another 20 minutes. Just pick it up and fry some.
