I also like this dish very much. It's a pity that ordering a plate in a hotel is not worth 100 yuan. Later, I went out to learn the same 1 made at home as in a hotel. Ketchup is the same as ketchup. The sauce on fish is not called sauce. Practice: Concentrated orange juice, tomato sauce and red Zhejiang vinegar are poured into the pot to fix the color, and then the sugar tastes good. If it is sour, just give sugar (red and Zhejiang vinegar is used for color matching). Set the taste, boil it, pour in the prepared water starch, stir well, rinse the oil and pour it on the set fish. 3) I think the fish is crispy outside and tender inside. When it is just fried, the oil temperature will be high. You can fry it once, then turn it over carefully with oil fishing, and then fry it slowly for 2 minutes with medium fire. The fish is crispy outside and tender inside.
