A classic banquet dish that relies on freshness and restraint. The fish is steamed whole to keep the flesh silky, then finished with a pour of soy sauce and a dramatic sizzle of smoking-hot oil that blooms the ginger and scallion on top.
Freshness is everything here. Press the fish: the flesh should spring back. Clear eyes, red gills, no fishy smell.
If your tilapia smells muddy, soak it in lightly salted water with a splash of Shaoxing for 15 minutes before cooking.
