INSTRUCTIONS

1. In a medium bowl whisk the sauce ingredients. 

2. Generously brush or spray the fillets with oil and season with salt and pepper to taste. Grill, flesh side down, over direct high heat (450F to 550°F), with the lid closed as much as possible, until you can lift the fillets with tongs off the grate without sticking, 6 to 8 minutes. Turn the fillets and cook them to desired doneness, 2 to 3 minutes for medium rare. Slide a spatula between the skin and flesh, and transfer the fillets to serving plates. Spoon the sauce over the fillets. Serve immediately.
