I am not bragging, (well I am) but I can't take credit for this recipe. I found it on all recipes. Last summer I bought a bunch of cedar planks for the grill. Well I finally got around to using them. I soaked the plank in water for about 5 hours. Then I had the supermarket skin 2 pounds of salmon filet and marinated it for about 4 hours in 1/3 cup salad oil, 1/3 cup soy sauce, a couple of tablespoons or more of Rice wine vinegar, 3 tablespoons of fresh ground ginger, a teaspoon of minced garlic, a bunch of chopped green onion, about 1/2 cup.
Set the grill at about medium so when the cover is closed, its about 400 degrees. Place the plank on the grill until it smokes slightly and you hear it crackle. Place the salmon on the plank, I add the marinade again at this point. Let it cook about 20 minutes until it flakes. Stand by with a spray bottle in case the edge of the plank catches on fire. It was great. It is good hot. It is good cold. DS who won't eat fish even liked it. I hope I can find more planks during the winter. We grill through the snow.

But I've made a very similar version of your salmon by marinating and tossing on the grill in foil. (We actually prefer it to be softer rather than crispy.) Instead of the ginger, we used garlic, and instead of vegetable oil, we use 1 tbsp of sesame oil. And we add 2 tbsps of brown sugar. Save some of the sauce for drizzling on the salmon. I'm not usually good at cooking fish, but we now eat this every week, pretty much.
Then I saw there was a backstory.
