Salmon with Brown Sugar Mustard Glaze

​1 tablespoon olive oil
1 large shallot, minced
¼ cup red-wine vinegar
¼ cup whole-grain mustard
¼ cup packed brown sugar
salt
pepper
4 center-cut skinless salmon fillets (6-8 ounces each), 1 to 1½ inches thick
 
1.  Heat broiler, with rack in top position, and line a baking sheet with foil. In a small saucepan, heat oil over medium-high. Add shallot and cook, stirring often until softened, 3 minutes. Add vinegar and cook until slightly evaporated, 1 minute.  Add mustard and brown sugar; stir until warm and combined, 1 minute. Season with salt and pepper and remove from heat.
​
2.  Place salmon fillets on prepared pan and season with salt and pepper.  Spoon about ½ cup glaze onto salmon, without touching raw fish with spoon, and brush to coat with pastry brush.  Broil until glaze is bubbling and fish is opaque throughout, 8 to 10 minutes.  Drizzle remaining glaze over fillets before serving.
