This is my mother-in-law's specialty:
1/2 pound salmon
1 teaspoon extra-virgin olive oil
1 teaspoon fresh lemon juice
1/8 teaspoon salt
Pinch freshly ground black pepper
2 cloves garlic, minced
1 teaspoon fresh rosemary leaves, chopped, or 1/2 teaspoon dried, crushed
Fresh rosemary sprigs (optional)
Cut the fish into 2 equal-size portions. Combine the olive oil, lemon juice, salt, pepper, garlic, and rosemary in a bowl. Brush the mixture onto the fish.
To grill, arrange the fish on a grill rack or use a grill basket sprayed with olive oil cooking spray. Grill over medium-hot coals until the fish flakes easily (allow 4–6 minutes per 1⁄2" of thickness). If the fish is more than 1" thick, gently turn it halfway through grilling.
To broil, spray the rack of a broiler pan with olive oil cooking spray and arrange the fish on it. Broil 4" from the heat for 4–6 minutes per 1⁄2" of thickness. If the fish is more than 1" thick, gently turn it halfway through broiling.
To serve, top the fish with capers, if using, and garnish with rosemary sprigs, if desired.
