• 24 ounce salmon fillet with skin ()
• 1 teaspoon sugar

Directions

1. Heat 1 tablespoon oil in a 12-inch nonstick skillet over medium heat until hot. Pat salmon dry and sprinkle with 1 teaspoon salt and 1/2 teaspoon pepper, then cook, skin side up, until undersides form a golden crust, 12 to 15 minutes. Turn fish over and cook until just cooked through, about 3 minutes more.
2. Meanwhile, heat remaining 2 tablespoons oil in a large skillet over medium-high heat until it shimmers, then sauté onions until golden brown and crisp-tender, 6 to 8 minutes. Stir in vinegar, sugar, and 1/2 teaspoon salt and cook until sauce is syrupy, about 2 minutes.
3. Remove from heat and stir in butter.
4. Spoon onions with sauce onto plates and top with salmon, skin side down.
