Ingredients: one cod, one garlic, one onion, flour and two tomatoes (without ketchup). Seasoning: oil, salt, soy sauce, vinegar, sugar, chicken essence. Practice: 1. The cod is shaved and sliced (one slice is enough for two people, too greasy). 2. Oil the pan, and the amount must be large. Then wrap the snow fish in a layer and fry until golden brown.
