1. Turn the sausage over, sprinkle a proper amount of flour on the inside and outside of the sausage, rub it clean, and then clean it with water for later use.

2. Put the prepared sausage in order, fold it at one end of the sausage 15cm, then put the sausage on the palm of your hand, and hold one end of the sausage in the other hand to wrap it tightly. After wrapping a bitter sausage at a time, fix it with clean cotton thread outside, and continue to wrap the bitter sausage at the back until all the bitter sausages are rolled up, and wrap all the bitter sausages from beginning to end.

3. When cooking bitter sausage, prepare a proper amount of marinade and water, and never add water while cooking. After the fire boils, put the wrapped pig intestines into the pot to boil, then turn to low heat and cook slowly for 3 minutes. After that, you can open the lid, but you can't take out the bitter sausage. After soaking in the marinade for 3 minutes, you can eat it.
