1. The casserole just bought needs to be treated. If it is boiled with rice washing water, it can prevent the casserole from bursting in use.

2. When the casserole is used for the first time, you need to brush off a lot of small sand grains on the inner wall of the casserole with a small brush to prevent the sand grains from falling into the food.

3. Newly bought casserole often leaks water, which is because there are many sand holes. When the new pot is used for the first time, it is best to make noodle soup or gruel. After eating, don't brush the pot first, set it on fire and bake it, so that the batter in the pot will dry up, plug the tiny sand holes on the pot wall, and then wash it. In this way, the casserole will not leak.

4. Do not quench when cooking. If you need to add water, you should also add hot water to avoid cold and hot shocks and reduce its service life.

Extended information:

When using the casserole, the following points should be noted:

First, the enamel of the casserole contains a small amount of lead, so it is best to soak the newly bought casserole in 4% vinegar water and boil it first, so that most harmful substances can be removed. If the inner wall of the casserole is colored, it is not suitable to store wine, vinegar, acidic drinks and food.

second, before using the new casserole, it is best to boil it with rice, which can block the tiny holes of the casserole, prevent water seepage and prolong its service life. Dry the water outside the casserole before each use. If you find that there is little water when cooking, you should add some warm water in time. Never spill or boil the soup in the pot. Casseroles should not be cooked in an empty pot, and the cold pot should not be suddenly placed on a prosperous fire to avoid the casserole from bursting.

Third, casserole is not suitable for cooking and cooking sticky food.

fourthly, the temperature of casserole is different from that of other types of pots. Generally, the cooking time in iron pan is strong fire-slow fire-strong fire, while the cooking in casserole is slow fire first, then strong fire, and after the soup is boiled, it is finally cooked with slow fire. After cooking, the casserole should be placed on a dry wooden board or straw mat, never on a ceramic tile or concrete floor, or the casserole will burst when it suddenly gets cold, which will easily burn people.
