Clean chestnuts, and then boil them in boiling water for 6 minutes. Take it out after cooking and put it in cold water for about 30 seconds. Chestnuts are easier to stir when they are still hot.
Then it's time to deal with the chicken. In the process of processing chicken, cut the chicken into pieces of uniform size, and then prepare a clean pot. You don't need to add cooking oil to the pot, just pour the chicken into the pot and stir fry. In the process of frying, try to keep the fire low. First, stir-fry the fat in the chicken. When you see that the state of the chicken is obviously shrinking, you can pour the prepared garlic slices and ginger slices into the pot and stir-fry them for fragrance. Then add seasoning, crystal sugar, thirteen spices, oyster sauce, soy sauce, soy sauce and cooking wine in turn, and stir well.
Next, add chestnut and stir fry, and finally add boiling water without ingredients. It should be noted here that boiled water must be added. If cold water is added, the meat will turn into firewood, which will affect the taste. When the fire boils, turn to low heat and simmer for about 10 minute. Finally, the soup is slightly dried with a big fire, sprinkled with an appropriate amount of onions and stirred evenly, and a delicious "roasted chicken with chestnuts" can be made.
