The lemon and basil marinade is thick enough to spread over the salmon fillet to marinate and to use as a basting sauce during grilling.
Place salmon in baking dish.
Combine basil, garlic, oil, rind, juice, salt and pepper in blender. Whirl until smooth paste. Spread half of basil mixture over salmon; reserve remaining half for basting. Turn salmon over to coat well. Marinate the salmon in the basil mixture for 30 minutes, turning after 15 minutes.
Prepare outdoor grill with hot coals, or heat gas grill to hot, or heat oven broiler. Grill salmon, basting with reserved marinade, for 4 to 5 minutes per side or until opaque in center. Transfer fish to plates. Serve with Spicy Corn Relish.
