Step 1

Stir soy sauce, maple syrup, vinegar, ginger and crushed red pepper in a baking dish.

Step 2

Lay salmon skinned side up in the marinade and refrigerate 30 minutes to 1 hour.

Step 3

Preheat oven to 425 degrees F. Line a large roasting pan or rimmed baking sheet with foil.

Step 4

Lay salmon on the foil, skinned side down. Roast until the fish is just barely cooked in the center for medium, about 9 to 15 minutes.

Step 5

Meanwhile, pour the marinade into a small saucepan and bring to a simmer over medium-high heat. Simmer until thick and syrupy, 6 to 9 minutes.

Step 6

Pour the reduction over the fish before serving.
