The new ceramic pot had better cook the rice porridge once, turn to boil after the water temperature, and simmer for 20 minutes with low fire, so that the tiny starch particles in the rice soup can penetrate into the cracks of the ceramics, and the ceramics are clean, firm and durable, which can increase the service life of ceramic pot by 30%. Attention, this pot of rice soup had better be emptied. Because it acts as a cleaner, the newly bought ceramic pot needs to be brushed with a hard brush. The pot wall has fine pores and good water absorption. You can fill the pot with clear water for 5 minutes, then wash it and dry it for later use. However, it should be noted that the soaking time should not be too long. Before you put ceramic pot on the fire, you should also dry the water outside the pot. When the newly bought casserole is used for the first time, it is best to cook porridge, or use it to cook thick rice washing water or noodle soup, so as to block the tiny pores of the casserole and prevent water seepage.
