Ingredients

  • 4 medium leeks
  • 1/4 cup white wine vinegar
  • 1/2 cup extra virgin olive oil
  • 1 teaspoon Dijon mustard
  • Salt to taste
  • Black pepper to taste
  • Fresh herbs (such as chives or parsley) for garnish

Steps

  1. Start by preparing the leeks: trim the roots and the tough dark green tops, leaving about 15 cm of the lighter green and white part. Rinse thoroughly to remove any dirt.

  2. In a large pot, bring salted water to a boil. Add the leeks and cook for about 10-12 minutes until tender but still firm. Drain and cool under running water to stop cooking.

  3. While the leeks cool, prepare the vinaigrette. In a bowl, whisk together the white wine vinegar, Dijon mustard, salt, and pepper. Gradually add the olive oil while whisking to create a stable emulsion.

  4. Once the leeks are cool, cut them in half lengthwise and arrange them on a serving plate. Drizzle the vinaigrette generously over the leeks.

  5. Garnish with fresh herbs and serve immediately or let the flavors meld for 30 minutes at room temperature before serving.

Why this works

The key to mastering Leeks Vinaigrette lies in the balance of textures and flavors. Cooking the leeks in salted water ensures they are tender and flavorful; however, be cautious not to overcook them, as they can become mushy. The vinaigrette, an emulsion of oil and vinegar, provides a zesty contrast that complements the leeks' mild sweetness. If the vinaigrette breaks and separates, simply whisk in a little more mustard or vinegar until it comes back together. This dish highlights the importance of fresh herbs, which add an aromatic finish, enhancing the overall experience. The vibrant colors and textures make it a visually appealing starter, embodying the essence of French bistro cuisine. Letting the dish sit for a while allows the vinaigrette to penetrate the leeks, intensifying the flavor profile.
