Casserole can transfer external heat energy to internal raw materials in a balanced and lasting way. Relatively balanced ambient temperature is beneficial to the mutual penetration of water molecules and food, and can release the taste of food to the maximum extent. These characteristics make it especially suitable for cooking soup, clay pot rice and other dishes that need to be simmered by young people. Casseroles can't be cooked, but cast iron pots can. Casserole is more suitable for cooking porridge because of the pores on the surface, and can absorb the impurities in porridge. Casserole porridge is the best, but it is easier to paste the pot, so it is very fulfilling to cook a good pot of porridge with casserole. The recommended recipes for casserole are casserole chicken, casserole fish head and so on.
