- Servings: 12
Source: Martha Stewart Living, September 2006
- 1 sprig fresh thyme
- Juice of 1/2 lemon
- Coarse salt
- 6 medium leeks, white and pale-green parts only, halved lengthwise and rinsed well
- 1 teaspoon Dijon mustard
- 2 teaspoons finely shredded (about 1/2 lemon total) lemon zest, plus 2 tablespoons fresh lemon juice
- 5 tablespoons extra-virgin olive oil
- 1/4 teaspoon coarse salt
- Freshly ground pepper
Make the poached leeks: Bring thyme, lemon juice, a large pinch of salt, and 5 quarts water to a boil in a large stockpot. Add leeks; reduce heat, and simmer until tender, about 15 minutes. Using tongs, transfer leeks to paper towels to drain; discard thyme and cooking liquid. Transfer leeks to a platter.
Make the vinaigrette: Whisk together mustard and lemon zest and juice in a small bowl. Add oil in a slow, steady stream, whisking until emulsified. Season with salt and pepper.
Pour vinaigrette over leeks. Let stand 30 minutes. Leeks can be refrigerated, covered, up to 2 days; bring to room temperature before serving.
