Production skills?
1. Stuff the dregs into the abdominal cavity of the fish, then combine the two fish pairs into the original state and put them into the bucket layer by layer. Other methods remain unchanged. The bucket of pickled fish should be placed in a dry place to prevent the bottom of the bucket from being dirty and rotten. After a few days, water seeps from the bucket, so don't start it. This brine can isolate the air and protect the flavor of pickled fish.
2. After curing for 3 months, you can generally eat. Every time you take food, take it out from the top and press it as it is.
