Does the casserole need to be boiled?

The casserole needs to be boiled. You can wipe the pan with oil. Heat it with a big fire. If there is lard, wipe the casserole with lard. Then rinse, ventilate and set aside. When the casserole is used, it should not be boiled quickly. If water is needed, it should be heated to avoid cold and hot shock, and it can't be dried, which will reduce the service life.

Because the casserole is a ceramic product made of raw materials that are not easy to transfer heat, such as seasonable, feldspar and clay, it is fired at high temperature and has the characteristics of air permeability, adsorption, uniform heat transfer and slow heat dissipation. Casserole can transfer the external heat energy to the internal raw materials in a balanced and lasting way. A relatively balanced ambient temperature is conducive to the mutual penetration of water molecules and food. The longer this mutual penetration lasts, the more delicious ingredients will overflow.

Matters needing attention in casserole purchase

1, look at the color: the color of high-quality casserole is mostly white, because white pottery is rich in iron oxide, and the artificially added pigment content is relatively small, so there are relatively few impurities. This casserole will not produce harmful ingredients after heating, and is more suitable for cooking food.

2, look at the shape: high-quality casserole structure is reasonable, the pot body is very symmetrical, very stable on the plane, will not shake. Then look at the lid, and we can turn it a little more. If the lid is smooth and tightly attached to the mouth when rotating, it shows that there is no problem with the structure of this casserole.
