Steamed Cod with Ginger and Scallions is a quick and simple recipe that called out to me the moment I saw it on Martha Stewart Everyday Food. It's a breeze to cook and requires less than 10 ingredients for great flavor with hardly any fuss.
In a deep sided saute pan, swirl together the rice vinegar (or stock), soy sauce, and ginger. Slice the cod into 4 fillets of the same size and season both sides of the fish with salt and pepper. Place the fillets in the pan and place over medium heat. Bring the liquid to a gentle boil, then cover and lower heat to a simmer. Cook for about 8 minutes, periodically spooning the liquid over the fillets.
Meanwhile, slice the scallions into three inch pieces crosswise. Take the green portions and thinly slice lengthwise. When the cod has steamed for about 8 minutes, scatter the scallions over the fillets and cover again. Cook for an additional 2 minutes, or until the fish is cooked through and opaque.
Serve immediately. I love this over rice noodles (which cook very quickly, 5 minutes or less) or steamed rice.
