Ingredients

Method

Preheat oven to 350°. Toast hazelnuts on a rimmed baking sheet, tossing occasionally, until golden brown, 8-10 minutes. Toss with 1 tablespoon oil; season with salt and pepper.

Meanwhile, heat remaining 2 tablespoons oil in a large cast-iron or nonstick skillet over medium-high heat until almost smoking. Season scallops with salt and pepper; cook until golden brown and just cooked through, about 3 minutes per side. Transfer to a plate.

Pour off most liquid in skillet. Add tomatoes and shallot, season with salt and pepper, and cook, tossing, until some tomatoes have burst, about 4 minutes. Mix in vinegar and serve with scallops topped with tarragon and hazelnuts.
