You need to treat the large intestine first. If you buy a cooked large intestine, it will be easier. Just cut it directly. But if you buy a raw large intestine, you need to clean it. You'd better add some flour to it. After cleaning, put the large intestine into the pot, add some water, boil it with high fire, then turn to medium fire and continue cooking for 3~5 minutes. It should be noted that the large intestine should not be cooked too badly, otherwise the dry pot fat intestine will not taste very good. You can find a toothpick to poke the large intestine. If the toothpick can easily poke into the large intestine, it proves that it is almost cooked. Take out the cooked large intestine, drain it and cut it into small pieces, about one centimeter long. Then put it on a plate and sprinkle some starch on it. Scrape evenly and set aside.
Boil the oil in the pot. The oil in the pot is hot. Put the large intestine in and fry it. Don't fry for too long, about 30 seconds, then take it out and put it aside. Deep-fry the large intestine with a small amount of oil, heat it, add some pepper and garlic, add some bean paste after it smells, stir-fry the red oil of the bean paste, and then put the large intestine in a pot and stir it evenly with high fire.
Then add the chopped string peppers and prickly ash into the pot, continue to stir-fry evenly with high fire, add some celery segments, stir-fry for a few times, then add soy sauce, edible salt and monosodium glutamate, and then you can take it out of the pot and put it on the plate, so that a very delicious dry pot of fat sausage is ready. In fact, the preparation method of this dish is extremely simple, but it may take some time to treat the large intestine. If you are lazy, you can go out and buy cooked large intestine that has been pickled.
