How to Make It
Preheat oven to 300°.
Carefully remove rind from lemon using a vegetable peeler; reserve lemon for another use. Coarsely chop rind. Place rind and capers on a baking sheet; bake at 300° for 15 minutes. Let caper mixture stand 10 minutes; finely chop. Stir in salt and pepper.
Heat oil in a large nonstick skillet over medium-high heat. Add fish to pan; cook 2 minutes on each side or until fish flakes easily when tested with a fork or until desired degree of doneness. Serve with caper mixture. Garnish with lemon wedges and parsley, if desired.
