I bought frozen silver cod from the supermarket, but I don't know how to do it. Try steamed silver cod. Cod meat is tender and melts in the mouth. It's good to eat too much spicy food, and occasionally eat this extremely light one. Practice: 1. Add salt, cooking wine, ginger, garlic, onion and pepper, and steam in a cage for 10 minute. 2. After steaming, take out the pot with ginger and garlic and season with soy sauce. 3. Add celery leaves and shredded onion, and you're done.
