Cleaning method of large intestine: steps:

1. Prepare ingredients:

A pig's large intestine, a handful of sweet potato powder (or raw powder, or salt, etc. ).

Just boil a pot of hot water first, and then boil it for later use.

3. Turn the fat sausage over, first remove the dirt and lymph attached to the oil, and leave a part of the oil, so that it tastes better.

4. Add some cold water to the spare boiled water, just a little warmer.

5. Rinse the fat sausage with warm water, then sprinkle a little sweet potato powder and wash it until it produces a lot of mucus. Wash with warm water and throw away the dirty water. Wash it repeatedly for 2-3 times, rinse it with warm water, turn the large intestine upside down, wash it in the same way for 2-3 times, and rinse it with warm water. There is almost no mucus and the taste is almost gone. It's clean enough for the next process. You can directly cut and fry. Whether it is fried or pickled, you like to blanch it in water first.

6. Put a proper amount of water into the pot, boil it, put it into the cleaned large intestine, and pour a bottle of cooking wine. When cooking, insert it easily with chopsticks and take it out.
