Seared Salmon with Balsamic Glaze

• 1/4 cup balsamic vinegar
• 1/4 cup water
• 1 1/2 Tbsp fresh lemon juice
• 4 tsp packed light brown sugar
• 4 (6-ounce) center-cut salmon fillets
• 2 tsp vegetable oil

1. Stir together vinegar, water, lemon juice, and brown sugar.
2. Pat salmon dry and season with salt and pepper.
3. Heat oil in a 12-inch nonstick skillet over moderately high heat until hot but not smoking. Increase heat to high and sear salmon, skin sides up, until well browned, ~4m. Turn fish over and sear until just cooked through, ~3-4m.
4. Transfer salmon to plates and carefully add vinegar mixture to skillet (liquid will bubble vigorously and steam). Simmer, stirring, until thickened and reduced to about 1/3 cup, ~2m.
5. Spoon glaze over salmon.
