Steamed Fish with Ginger and Scallion (薑蔥蒸魚)

Steamed whole fish with ginger and scallion is one of the most important dishes in Cantonese cooking. It appears at banquets, at New Year dinners, and on weeknight tables, and it is a test of two things: the freshness of the fish and the restraint of the cook. A good steamed fish needs almost nothing. Ginger, scallion, soy sauce, and hot oil. The fish does the rest.

The technique has a moment that defines it. After the fish is steamed, the cooking liquid is poured off, julienned ginger and scallion strips are laid across the top, and then smoking hot oil is poured directly over them. The oil hits the aromatics and they sizzle violently, blooming their flavor in an instant and infusing the fish with a fragrance that steaming alone cannot produce. That sizzle, that thirty-second burst of aroma, is the reason this dish exists in the form it does.

The fish steams for about twelve minutes on high heat, which is enough for a fish of about one and a half pounds. The eyes turning white is the traditional doneness indicator. Oversteaming by even two minutes produces fish that is dry and chalky rather than moist and silky. A cut along the backbone of a whole fish helps the thicker side cook evenly. The sauce, a mixture of light and dark soy sauce, cooking wine, white pepper, sugar, and water, goes on after the hot oil. Sesame oil and fresh cilantro finish the plate.
