Grilled Salmon with Lemon-Pepper Compound Butter

"Salmon has hearty, firm flesh that makes it an excellent choice for grilling. In this easy recipe, we add fresh, bright flavor to the fish with a compound butter: Mix softened butter with lemon zest, garlic, and plenty of black pepper, then chill. When you’re ready to grill the fish, give it a simple seasoning of salt, pepper, and vegetable oil. After about 10 minutes on the grill, the salmon will have crispy skin and a moist interior ready to be topped with a melty pat of the flavorful butter. Game plan: The butter can be wrapped tightly in plastic wrap and frozen for up to 1 month. Use any left over to spread on buttermilk biscuits, toss with hot pasta, or top roasted asparagus. To keep the fish from sticking to the grill, once the grill is hot, use the scraper to remove any residue from previous grilling sessions. Then follow the instructions here for oiling the grill right before cooking...."
