Steps for making Braised Spanish Mackerel with Shiitake Mushrooms：Prepare the ingredients: Spanish mackerel and shiitake mushrooms. Cut the Spanish mackerel into sections, slice the shiitake mushrooms, and slice the scallions, ginger, and garlic. Pour oil into the pan, and fry the Spanish mackerel until golden brown on both sides. Add the scallions, ginger, and garlic, and stir-fry until fragrant. Splash in cooking wine to remove the fishy smell. Add water, sugar, rice vinegar, light soy sauce, and dark soy sauce for seasoning. After simmering for a few minutes, add the shiitake mushrooms and simmer. When the sauce has reduced and thickened, add salt, turn off the heat, and serve.
