First of all, it doesn't have to be too complex, but the way the stew is made is decisive for the taste. I've done it with frying pots, electric pots, pots of ceramic sand, mud casseroles, of which the mud casserole tastes the best, which can be described as sour, and, secondly, because ketchup oxen can drink soup, sugar must be added to the sour taste of the medium and tomato。
