Ingredients: a grass carp, shredded onion, ginger, salt and pepper. Sauce: peas, chopped green peppers, chopped red peppers, chopped mushrooms, corn kernels, diced mushrooms, tomato sauce, white sugar, white vinegar, salt and water starch. Practice: 1, after the fish is cleaned, cut off the head and tail, cut it into thin slices from the back of the fish, and don't cut off the abdomen, so that the cut fillets are connected in the abdomen. 2. Put ginger slices and shredded onion on the plate, spread the cut fish out in a circle, leave a circle at the place where the abdomen is connected, put the fish head, put the fish tail in the spare position in the middle of the fish body, or use it for other purposes, and marinate the fish body with a little salt and pepper for a while. 3. Steam in a boiling water pot for 6-7 minutes (adjust according to the size of the fish and the thickness of the slices), turn off the fire, simmer for 2-3 minutes, then open the lid and pour out the water in the plate. 4, another pot, stir-fry ginger and garlic under oil heat, add diced mushrooms, corn kernels and peas, stir well, add a little water and cook slightly. 5, chopped green and red pepper, pour tomato sauce, sugar, white vinegar and salt, stir well, then pour water starch to collect juice. 6. Pour the seasoning juice on the fish. Note: 1, generally, when buying fish, please ask the merchant to help kill the fish and clean it up. Please try to cut the knife straight when opening the chest, that is, just cut it from the middle of the abdomen, and try not to cross it. 2, cut the fish fillets yourself, the knife is very important, and the sharp knife is necessary, so it will get twice the result with half the effort when cutting fish. 3, the most difficult place to cut fish fillets is the big thorn in the back, so be careful when cutting. 4. The cut fish fillets should be as thin and consistent as possible. 5, such a modeling fish, it is better to use a flat fish, such as Wuchang fish. When I bought fish, I only had grass carp, which was big and fleshy, so it was not easy to cut. 5, it is not difficult to make such a shape, but it looks very festive, definitely the right amount of holiday table.
