1, remove the fish from the viscera and wash and drain, fish if large can be cut into sections.
2, the fish will be fried, both sides were golden brown out of the pan to be used. (Beforehand, we can use ginger to rub the bottom of the pan, the oil is hot and then the fish in the pan, so do not love to stick to the bottom of the pan).
3, the pot on the bottom of the oil, the onion, ginger, garlic, dashi under the pot popping aroma, put the right amount of soy sauce, add water, and then into the fish. The water should not exceed the fish.
4, the water boiled into the cooking wine, rock sugar, salt, tomato sauce. (I put 15-20 pieces of rock sugar for these fish).
5, finally, even the soup with fish into the pressure cooker pressure 20-30 minutes after it is done. (Note that the water should not be put less, to not over the fish).
