The ingredients are a duck (frozen), a potato, five or six mushrooms, a green pepper and a bottle of beer duck.

One star anise (also known as spiced and aniseed), three slices of ginger, a small piece of old ginger, two garlic cloves, a handful of green onion, chopped green onion and chopped green onion leaves. Production steps 1, duck chop, wash blood (frozen duck should be soaked in cold water until it is frozen). Fill the pot with cold water, add chopped ginger, boil over high fire, pour out the duck pieces and drain, pick out the ginger, wash the pot and dry it. 2. Heat the oil in the pan, put the garlic cloves, scallion segments, star anise and ginger slices in the frying pan, pour the duck pieces and add a little soy sauce to stir fry. Pour the whole bottle of beer, cover it with a little vinegar (vinegar meat is easy to rot), boil it over high heat (cut potatoes, mushrooms and green peppers into pieces, and the potato pieces can be larger for later use), and cook for a while, so that the soup looks thicker. 3, change to a small fire and simmer slowly. When the soup is left half, add potato pieces and mushrooms, change the fire and boil it and then transfer it back to a small fire. 4. Put salt when the potatoes are half cooked. After three minutes, change the fire, put green peppers, add a little salad oil (to increase the color of the dishes), put appropriate soy sauce, and stir fry until the soup is collected. Put the chicken essence in the pan, put it on the plate and sprinkle with chopped green onion. Precautions 1, you can't thaw with hot water in a hurry, it won't rot with hot water. Potato pieces should not be too small. Pay attention to the time when burning. If the time is short, the potatoes will not be enough. If they grow, they will paste into a pile. It is better to be soft but not scattered. 2. The smell of duck meat is heavy. First blanch it with boiling water, and then stir-fry it in the pot until it is oily. This method can eliminate the smell of duck meat. The stewed duck meat is delicious and the soup is fragrant and delicious. 3. Stew duck meat with beer. Duck soup will have a strong beer flavor, but the wine flavor will gradually disappear after long cooking. Eating duck meat without soup will not be intoxicating. 4, the amount of spices should be less than more, the purpose is to enhance the fresh flavor of beer ducks, and putting too much spices is easy to grab the main flavor.
