Method 1: The general habit is to treat fresh bracken with rice soup or rice washing water to remove bitterness; Dried bracken can also be used in this way; In addition, it is also good to soak your hair with water and a little sugar.
Method 2: soak the dried bracken to remove impurities and astringency and make it soft. The method is to wash the dried bracken with clear water for several times to remove impurities such as sand, and then soak it in clear water for 8 hours. After 8 hours, don't pour out the clear water, put it in the pot and cook for 5 minutes. After boiling, leave the water in the pot and continue to soak it in dried bracken 12 hours, and then use it for later use. If you can't finish the soaked bracken, you can put it in the refrigerator and use it when necessary.
Method 3: blanch with boiling water before soaking, remove the old part after 24 hours, and then cook with clear water 15 minutes. If it is pure natural bracken, it will naturally air-dry during processing, so it is inevitable that there will be some dust or small impurities, so it must be rinsed twice with warm water before soaking. If it is to be fried, it is best to soak it in water of about 50 degrees. When soaking, make sure that water does not flow through the air-dried bracken, so that the bracken can be fully soaked. At the same time, if the water is cold, it is suggested to change it again. When people in Enshi, Hubei generally want to eat, they soak in the first night, change hot water in the middle, and eat at noon or afternoon the next day. Otherwise, the soaking time must be longer. If it is stew or soup, clean it directly with warm water, cut it into small pieces and put it in the pot for processing. Pteridium aquilinum will absorb a small amount of water when it expands, so put more water when making it.
