The first step is to deal with oysters. Add 1 tablespoon of cornstarch to the oyster meat, rub it for a while to remove the slime on the surface, and then rinse it in a hurry. Add a little bit of cooking wine and set aside.
Step 2, wash and chop the chicken into small pieces. Prepare a pot of cold water, put the chicken pieces, ginger, high heat to boil, cook out the foam and fish out the chicken pieces. Then prepare another cast iron pot, pour a little oil and heat, when the oil is hot, under the ginger, green onion burst the flavor. Then put the chicken pieces together and stir fry for a minute. Chicken over the oil fried soup will be more flavorful and mellow. In the fried chicken add hot water not over the chicken, open high heat to boil. After boiling, turn to low heat and simmer for 60-90 minutes, you can also cook a little longer, the soup is more concentrated.
