I have two stews. One is made in hals, and the other belongs to a Japanese cooking teacher. First of all, it must be affirmed that there is basically no difference between domestic cups and Japanese cups. Then answer the question of the subject, is there a necessary premise that is demand? If you are a single young man who likes to sleep late and wants a hot breakfast, it is necessary. In my own experience, I can only think of such a scene. I bought tremella porridge because I watched a health program and said it was good. I am too lazy to do it myself. I also tried millet porridge with a little alkali, and the effect is no different from that of a rice cooker. I bought hals first, but the cooking teacher just thinks that the foreign moon is round after all. If you bring rice, don't think about it. Whether it is rice or vegetables, it will only become difficult to swallow in it. There is another point that was not mentioned in the propaganda. If you want to achieve the effect of the stew, you must warm the cup, that is, fill it with boiling water and heat it first, otherwise you can't cook an egg.
