Put some salt in the water when cleaning, and the dirty things will be spit out, so you don't have to gut them. You can directly fry or put some noodles!
Don't eat. This is a dirty thing. Shit or something, we ate together without cleaning up. Well, although it smells good with seasoning, it is still bloody in essence.
Put some water in the basin, and then put the loach in it, so that the mud in the loach's stomach will spit out after a long time. The longer the time, the cleaner it is. When the water in the basin is no longer turbid, you can cook in the pot. Snails are washed in this way.
