Why does the casserole crack?

First of all, we need to see if it is a quality problem. Generally, the main reason for the cracking of a casserole is poor heat transfer. It is easy to crack due to uneven heating and cooling. The temperature should be raised slowly and not kept for a long time. Do not use a casserole to cook things that are too sticky. The water in the casserole cannot be boiled dry. Keep the casserole not too dry. Do not use high heat to cook food with cold water or ice right away. Slowly heat the casserole over low heat before switching to high heat. This way, the casserole will not crack or fall off.

Question 1

If the casserole is not used properly, it can be easily damaged. A newly bought clay pot usually has a lot of sand stuck to the inner wall, which needs to be brushed off with a harder brush;

Question 2

The pot wall has tiny pores and is water absorbent. The pot can be filled with clean water and left for 3 to 5 minutes, then washed and dried for later use. But be careful, the soaking time should not be too long, otherwise it will absorb too much water and the casserole will explode when exposed to fire. Before putting the casserole on the fire to cook anything, you should also wipe off the water on the surface of the pot. When cooking, use warm water first, then switch to high heat after the soup is hot, and then switch to low heat after the soup boils. When the casserole is cooking, if there is less soup in the pot, add water, never add cold water, but warm or hot water.

Question 3

The soup in the pot must not overflow to prevent the outside of the pot from getting wet and bursting. In addition, if you are using a coal stove to heat, be sure to prevent the bottom of the casserole from rubbing against the coal. The casserole is brittle and easily broken, so it should be handled with care. It is best to place a hot casserole that has just been used on an iron rack, and not on wet ground, tiles or concrete floors, otherwise the temperature will change suddenly and the casserole will easily explode. When using a newly bought clay pot for the first time, it is best to use it to cook porridge, or use it to boil thick rice water to block the tiny pores of the clay pot and prevent water seepage. Before each use, wipe off the water on the outside of the casserole. If you find that there is less water when cooking, add some warm water in time. Never let the soup in the pot overflow or dry up.

Question 4

When using a casserole to make soup or stew meat, first put water in the casserole, then place the casserole on the fire, first using a low heat and then a high heat. When taking the casserole off the fire, place it on a dry wooden board or straw mat, and never on a tile or concrete floor. Do not use a casserole to cook thick pastes.
