First, dry cleaning
Don't touch the water first, and don't touch a drop of water (the water on it itself is fine before you buy it back). Put it in a big basin, and add flour according to the amount. The amount of flour should be as much as possible, so it is advisable to wrap all the fat sausages, so dry rub them without adding water, and turn out the inside of the fat sausages and rub them hard. Anyway, it will take a long time.
Second, washing
Wash it hard with clean water again, and the dirty things in the fat intestines will be washed away with flour paste and water.
Third, drowning
What I did before was to get rid of the visible dirty things, and then I wanted to get rid of the smell. After washing the fat sausage, I put it in a cold water pot. Add wine, ginger, onion and pepper to the pot, and boil it over high heat (don't cover the pot when cooking, let the smell out). It takes about 45 minutes to cook, and then you can take it out and make the fat sausage dishes you want to cook.
