Preheat oven to 425°. Cut salmon into 4 portions; place in a foil-lined 15x10x1-in. pan. Sprinkle with salt and pepper. Roast 10 minutes. Remove from oven; preheat broiler.
In a small saucepan, mix remaining ingredients; bring just to a boil. Brush over salmon. Broil salmon 6 in. from heat until fish just begins to flake easily with a fork, 1-2 minutes.
