Ingredients

1-1/2 pints fresh raspberries1/4 cup water2 tablespoons brown sugar1 tablespoon balsamic vinegar1 teaspoon salt, divided1/8 teaspoon plus 1/2 teaspoon coarsely ground pepper, divided 1/4 cup butter, softened4 cod fillets (6 ounces each) 2 tablespoons canola oilFresh minced mint leaves, optional

Preparation

Preheat oven to 375°. Reserve 1/2 cup raspberries. In a small saucepan, combine water, brown sugar, vinegar and remaining raspberries; bring to a boil. Reduce heat; simmer, covered, until sugar is dissolved and raspberries have broken down, 4-6 minutes, stirring occasionally. Press raspberry mixture through a fine-mesh strainer into a bowl; discard seeds. Stir in 1/2 teaspoon salt and 1/8 teaspoon pepper; return to pan. Bring to a boil. Reduce heat; simmer, uncovered, until liquid is reduced to 1/2 cup, 2-3 minutes.

In a small bowl, stir butter until smooth. Stir in remaining salt and pepper. Spread butter mixture over fillets.

In a large cast-iron or other ovenproof skillet, heat oil over medium heat. Add fillets; cook 1-2 minutes on each side. Bake until fish just begins to flake easily with a fork, 6-8 minutes. Serve with sauce. Top with reserved raspberries and, if desired, mint.
