2 medium fennel bulbs—halved, cored and finely chopped, plus 2 tablespoons
coarsely chopped fennel fronds
2 tablespoons sweet wine vinegar, such as Late Harvest Riesling, or seasoned
2 tablespoons fresh lemon juice
Salt and freshly ground pepper
In a large skillet, heat the olive oil until shimmering. Add the chopped fennel bulbs and cook over moderately high heat, stirring frequently, until golden and tender, 8 to 10 minutes. Let the chopped fennel cool in the skillet for 10 minutes, then stir in the vinegar and lemon juice and season with salt and pepper. Reheat and stir in the fennel fronds just before serving.
