Step 1

Preheat the oven to 225° F.

Step 2

Combine the sugar, soy sauce, rice wine, and water and heat for 1 minute in the microwave. Stir to dissolve the sugar.

Step 3

Line a small baking dish with the scallions and ginger and place salmon on top, skin side down. Season the salmon liberally with kosher salt and coat with oil. Pour the soy sauce mixture over the fish.

Step 4

Roast the salmon for about 50 minutes, or until a thermometer stuck into the thickest part reads 110-120° F. The fish should still look a lot like how it did when it went in (so, almost translucent). If you don't have a thermometer, check for doneness by poking the thickest part; it will start to flake once it is ready.

Step 5

Serve with rice and spoon some of the sauce on top for extra saucy goodness.
