1 stick unsalted butter
1/3 cup honey
1/3 cup packed brown sugar
1 Tbsp. fresh lemon juice
1 tsp. natural liquid smoke flavoring
3/4 tsp. crushed red pepper flakes
1 center cut salmon fillet, about 2 lbs., skin on, in one piece

Combine butter, honey, brown sugar, lemon juice, liquid smoke and red pepper flakes in a saucepan. Cook over medium heat, stirring, until smooth, about 5-7 minutes. Cool to room temperature. Arrange salmon on a dish large enough to hold it. Pour cooled marinade over it, let stand 30 minutes, turning once. Prepare hot coals for grilling. Oil grill well. Cook salmon, skin side up, over medium heat for 5-7 minutes. Then turn it over and cook until the fish flakes easily, another 5-7 minutes. Transfer to a warm platter and serve immediately. Serves 4.
