Can the oil in the intestines of beef offal be eaten? Do you want to scrape the oil clean when washing? There is a layer of yellow grease outside the intestine, which is unnecessary.
Be sure to wash it off, or you can't eat it. Internal organs are detoxified and must be cleaned before eating. The large intestine is the same as the stomach. I suggest you scrape them off with a knife first and dispose of them in a big place. Fine dirt can be washed with flour, which has strong adsorption capacity and is suitable for washing internal organs.
