First: wash the fat intestines with clear water before and after, and use chopsticks to help when turning the intestines;

Second: rub with salt, then rinse with water, and repeat two or three times;

Third: this is a trick. Soak the fat sausage cleaned in the first two steps in cooled tea for five to ten minutes.

The fat sausage treated in this way not only has no peculiar smell, but also has a faint tea smell after cooking. I hope I can help.
