What if there is a little sand in the old casserole for porridge?

1. If it's the first time to use the casserole, it's best to cook thick rice porridge first to block the tiny cracks in the casserole to prevent water seepage. If there are cracks, you can cook rice porridge again to repair them.

2. Casseroles are most afraid of hot and cold changes. In order to avoid bursting the pot, the water outside the pot must be fully dried before getting angry. You can use a small hot pot at first, and then turn to medium heat to gradually heat up.

3. When the casserole is served, it should be placed on a dry wooden board or straw mat, not in a cold place such as ceramic tile floor or cement floor.

After use, wait for natural cooling before cleaning. Don't soak for a long time, or the casserole will be moldy and smelly if it inhales sewage. Dry it after washing, put it in a cool and ventilated place, and then store it.
