After soaking the mushrooms in water, make a base, slice the potatoes, spread them evenly, and add appropriate amount of water to simmer (it is best to use an induction cooker). If it's a vegetarian pot, just add onions without ginger. In June and July, when it is ripe, add a proper amount of broth, and do not season it yourself with broth. Shred the onion. When the pan is about to take off, stir-fry the onion with oil and pour it in. If meat is added, blanch the meat, make it into a base with mushrooms, and add onion, ginger and yellow wine; Pour shredded pork or sliced meat before or at the same time as the onion. Note: this is the practice of non-professional chefs, which is more suitable for home cooking.
