Leeks Mimosa with Toasted Hazelnut (courtesy of Martha Stewart)
- 6 large leeks (3 pounds), white and pale-green parts only, halved lengthwise and rinsed well
- Coarse salt and freshly ground pepper
- 2 large eggs
- 1 teaspoon Dijon mustard
- 2 teaspoons finely grated orange zest, plus more for garnish
- 3 tablespoons fresh orange juice
- 1 tablespoon fresh lemon juice
- 1 tablespoon minced shallot
- 3 tablespoons extra-virgin olive oil, plus more for brushing
- 1 ounce (1/4 cup) skinless hazelnuts, toasted and chopped
- Preheat oven to 400 degrees. Arrange leeks on a rimmed baking sheet, and brush generously with oil. Season with salt and pepper. Roast, flipping once, until tender and gold, about 20 minutes. Let cool slightly on sheet.
- Meanwhile, place eggs in a medium saucepan, cover with cold water, and bring to a boil. Prepare an ice-water bath. Remove from heat; let eggs stand in the water for 12 minutes. Transfer eggs to ice-water bath to cool for 10 minutes. Halve eggs and remove yolks. Finely grate whites on the medium holes of a box grater; place in a small bowl. Grate or crumble yolks; place in another small bowl.
- Whisk together mustard, orange zest and juice, lemon juice, and shallot. Slowly add oil, whisking until emulsified. Season with salt and pepper.
- Arrange leeks on a platter. Scatter whites and yolks on top. Drizzle with vinaigrette. Sprinkle with hazelnuts, and garnish with orange zest. Serve immediately.
