1. Wash the fish, cut two knives on both sides of the fish body (the depth is close to the fish bone), wipe with Shao wine and fine salt and marinate slightly.

2, wok fire, oil burned to 70% heat, fish slightly fried. Leave 75g of oil in the pot, stir-fry Danxian watercress powder, ginger and garlic until the oil turns red, add fish and stock, move to low heat, add soy sauce, sugar and salt, cook the fish and put it on a plate.

3. Put the original pot on the fire, thicken it with wet starch, pour vinegar, sprinkle chopped green onion and pour it on the fish. Note: fresh crucian carp or mandarin fish must be used as raw materials. The marinade should be thick when cooking, so that the fish can stick to the marinade and taste it.
