Works best on the grill for a whole fillet with skin on. Smaller pieces can be roasted in a 400 oven. With this preparation you cannot turn the fish.
3/4 cup apple cider
6 Tbs. soy sauce
2 Tbs. unsalted butter
1 clove garlic -- pressed
Whole salmon fillet
Combine cider and soy in non-reactive pan. Bring to a boil, reduce to medium and cook for 3 minutes.
Add butter and garlic. Cook until sauce is thick enough to coat the back of a spoon. Cool for 30 minutes
Brush marinade over salmon, let sit 30 minutes then cook on grill.
