I just steam it and stir fry it. Anyway, you can treat it as an eel. Another way is to dry it first, then cut it into pieces, boil it in boiling soup for three to five minutes, and then add seasoning according to your own taste and stir fry it. As for the price, I don't have any farmed ones here. They are all wild, 7 yuan a catty, and the farmed ones are at least 2 yuan cheaper, which is estimated to be 4 to 5 yuan.
