Don't pour cold water into the crock when it is overheated. Similarly, if you put the crock in the refrigerator or outdoors at a low temperature, you can't pour overheated water.

1. When the newly bought crock is used for the first time, it is best to cook porridge or use it to cook concentrated rice washing water, so as to block the tiny pores of the crock and prevent water seepage.

2. When boiling the stew in a crock, you should first add water to the casserole, then put the casserole on the fire, first with slow fire, then with strong fire.

3. When putting the crock down from the top of the fire, put it on a dry wooden board or straw mat, and never put it on a ceramic tile or concrete floor.

4. Don't cook sticky food in a crock pot.
