Extended data:
Casserole is a kind of cooker. Traditional casserole is a ceramic product made of raw materials that are not easy to transfer heat, such as seasonable, feldspar and clay. Fired at high temperature, it has the characteristics of air permeability, adsorption, uniform heat transfer and slow heat dissipation. The recipes that depend on casserole include casserole chicken, casserole tofu, casserole fish head and so on.
Due to the problems of manufacturing technology and raw materials, the traditional casserole is not resistant to the change of temperature difference, easy to burst and cannot be dry-burned. Aiming at this problem of traditional casserole, in recent ten years, after research and improvement, spodumene was added into raw materials to make a high-temperature resistant casserole, which can withstand hundreds of degrees of high temperature without cracking while maintaining its original advantages, greatly improving the practicality of casserole.
Matters needing attention when using casserole:
1. When choosing to buy a casserole, it is best to buy a white casserole, because the more beautiful and bright the casserole, the more heavy metals it contains, which will affect human health after eating.
2. In order to prevent the casserole from leaking, the newly bought casserole can be used to cook porridge or rice washing water when it is used for the first time, because there are many small holes in the casserole, and boiling with rice washing water can block the holes in the casserole to prevent the casserole from leaking when it is used.
3. When using an iron pan to cook the meat or cook soup, you usually add oil first, heat the iron pan, and then add meat or oil. But when using the casserole, after putting the meat into the pot, add water first, and then put the casserole on the fire to avoid damage to the casserole.
4.？ When using the casserole, when the water in the casserole boils and the casserole comes down from above the fire, don't put the casserole directly on the tile or floor, but put the casserole on the wooden board, because the temperature of the floor or tile is very low, and the casserole with high temperature suddenly touches the floor with low temperature, which is easy to shorten the service life of the casserole.
5.？ When cooking porridge in a casserole, it is best to turn the porridge in the casserole upside down, because the impact of the wooden shovel on the casserole is relatively small, which can prolong the service life of the casserole. When cooking porridge, if it takes a long time, you can set the time for the alarm clock first, and then do other things. This will prevent the casserole from cracking.
6.？ When using a casserole, it is best not to cook acidic food in the casserole, because acidic food will dissolve the heavy metal substances contained in the casserole in the food, which will affect health after eating.
7.？ The essence of casserole is soil, which is refined from soil embryo at high temperature. Therefore, when using the casserole, it is best to handle it gently so as not to damage the casserole. When the casserole is boiling soup, if water is needed, it is best to heat the water to avoid cracking of the casserole due to excessive temperature difference.
