1, casserole. When making soup, you can also choose a delicate texture, white inner wall of the casserole, do not use low-quality casserole, because low-quality casserole enamel contains a small amount of lead, easy to dissolve out when cooking acidic food, harmful to health. Newly purchased casserole should be soaked in rice-washing water for one night, so that the starch material penetrates into the pores of the casserole, so that its capillaries are more compact. The casserole should not be burnt empty, before putting the casserole on the stove, the ingredients to be cooked must be put in first, meanwhile it must be cooked on a low flame first, and then turn to medium-high flame after the soup in the pot is boiled. If you need to add water during the cooking process, you should add warm water, because the temperature difference between the cold water and the soup in the pot is too big to cause the casserole to blow up.

2, tile pot. In the south, soup to use the majority of tile pot, because the tile pot is not easy to heat transfer of quartz, feldspar, clay and other raw materials with the clay, after high-temperature firing and become, aeration, dependence on good, but also has a uniform heat transfer, heat dissipation is slow and so on. When making soup, tile pots can transfer the external heat to the internal materials in a balanced and long-lasting way, making the soup taste more fresh and mellow, and the ingredients more easily crispy. Never put the wajian directly on the marble table or tile floor, the temperature difference will cause the wajian to explode. You need to wait for the temperature of the pot to decrease to a less hot level before cleaning it.
