1 1/2 pound wild-caught salmon (sockeye or coho)
1 tablespoon oil
1 tablespoon ginger, grated
1 tablespoon garlic, minced
1 tablespoon rice vinegar
2 tablespoons soy sauce
5 tablespoons honey
1 tablespoon sesame oil
1/4 teaspoon red pepper flakes
1 teaspoon toasted sesame seeds
1 scallion, thinly sliced (greens only)
Position a rack in the center of the oven and preheat the oven to 375F. Tear three pieces of foil that are slightly larger than the baking sheet, large enough to wrap the salmon in. Place one piece of foil on the baking sheet, followed by the second one going the other way (like a cross) and the last one going the same direction as the first. This will ensure none of the sauce leaks out.
In a saucepan over medium heat, heat the oil and add the ginger and garlic and allow to sizzle for just 30 seconds, add the rice vinegar and soy sauce and allow the them to reduce for 30 seconds to a minute. Stir in the honey and remove from heat. Add the sesame oil and red pepper flakes.
Place the salmon filet in the prepared foil, using a brush or spoon, brush the salmon with the sesame ginger sauce. Any remaining sauce can be poured around the salmon. Sprinkle with the toasted sesame seeds. Wrap the foil so all sides are properly closed so the sauce does not leak.
Bake salmon for 12-14 minutes or until firm (see note). Open the foil, spoon the sauce surrounding the salmon onto the fish, place under the broiler on for the 1-3 minutes, keeping an eye on the salmon so it does not burn. Remove from the oven, if your sauce is a little liquidy, allow the fish to rest for just 5 minutes. This will allow the sauce to thicken a bit. Serve with sliced scallions garnished on top.
