This salmon will sing when accompanied with Lime Butter Sauce (Recipe follows). From Gourmet Magazine.
Prepare grill for cooking over medium-hot charcoal (moderate heat for gas).
Season salmon all over with salt and pepper, then grill, flesh sides down, on lightly oiled grill rack (covered only if using gas grill) 4 minutes.
Sprinkle fillets with zest and top each with 1 tablespoon lime butter sauce.
Purée garlic with lime juice, salt, and pepper in a blender until smooth.
With motor running, add melted butter and blend until emulsified, about 30 seconds.
If you aren't able to grill outdoors, salmon can be cooked in a hot lightly oiled well-seasoned large (2-burner) ridged grill pan over moderately high heat.
