Recipe: Leeks Vinaigrette with Sauce Gribiche

Serves: 4 Prep Time: 20 minutes Cooking Time: 15-20 minutes (mostly for the leeks)

Ingredients:

For the Leeks:

• 4 medium-sized leeks, white and light green parts only
• Water, for blanching
• Salt
• Freshly ground white pepper

For the Vinaigrette:

• 3 tablespoons extra virgin olive oil
• 1 tablespoon red wine vinegar
• 1 teaspoon Dijon mustard
• 1 tablespoon finely chopped shallots
• 1 tablespoon finely chopped fresh parsley
• Salt and freshly ground black pepper, to taste

For the Sauce Gribiche:

• 2 large hard-boiled eggs, yolks and whites separated
• 1 tablespoon Dijon mustard
• 2 tablespoons white wine vinegar
• 1/2 cup neutral oil (like grapeseed or canola)
• 2 tablespoons finely chopped cornichons (French pickles)
• 2 tablespoons finely chopped capers, rinsed
• 2 tablespoons finely chopped fresh parsley
• 1 tablespoon finely chopped fresh chives
• 1 tablespoon finely chopped fresh tarragon (optional but recommended)
• Salt and freshly ground white pepper, to taste

Instructions:

1. Prepare the Leeks:

• Cleaning: Trim the root end of the leeks, leaving enough to hold the layers together. Cut off the dark green tops (reserve for stock if desired). Thoroughly wash the white and light green parts of the leeks under cold running water, making sure to get rid of any dirt or grit that may be trapped between the layers. You can make a slit lengthwise down the leek to aid in cleaning.
• Blanching: Bring a large pot of salted water to a boil. Gently place the leeks into the boiling water. Cook until the leeks are tender but still slightly firm, about 10-15 minutes. The exact time will depend on the thickness of the leeks. Check for doneness with a paring knife; it should slide in with minimal resistance.
• Cooling: Immediately transfer the leeks to an ice bath to stop the cooking process and preserve their color. Let them cool completely.
• Draining: Once cooled, remove the leeks from the ice bath and drain them well. Pat them dry with paper towels.

2. Make the Vinaigrette:

• In a small bowl, whisk together the olive oil, red wine vinegar, Dijon mustard, shallots, and parsley. Season with salt and black pepper to taste. Adjust the balance of oil and vinegar to your preference – it should be bright and slightly acidic.

3. Make the Sauce Gribiche:

• Yolk Base: In a medium bowl, mash the hard-boiled egg yolks with the Dijon mustard and white wine vinegar until smooth.
• Emulsification: Gradually whisk in the neutral oil, a little at a time, just as you would when making mayonnaise. Whisk vigorously until the mixture is emulsified and thick.
• Add the Mix-Ins: Finely chop the hard-boiled egg whites. Gently fold in the chopped egg whites, cornichons, capers, parsley, chives, and tarragon (if using).
• Seasoning: Season the sauce Gribiche with salt and white pepper to taste. Adjust the acidity with a little more vinegar if needed. The Gribiche should be tangy, rich, and full of texture.

4. Assemble and Serve:

• Cut the Leeks: Cut each leek lengthwise in half.
• Arrange: Arrange the leek halves on a serving platter or individual plates.
• Dressing: Drizzle the vinaigrette generously over the leeks.
• Top with Gribiche: Spoon a generous amount of Sauce Gribiche over the dressed leeks.
• Garnish (Optional): Garnish with a sprinkle of fresh parsley or chives, and perhaps a grind of fresh black pepper.

Chef's Tips and Variations:

• Leek Prep: Don't skip the thorough cleaning of the leeks. Gritty leeks can ruin the dish.
• Cooking Leeks: Be careful not to overcook the leeks, as they will become mushy. Aim for a tender but slightly firm texture.
• Vinaigrette: Feel free to experiment with different vinegars. Sherry vinegar or white balsamic would also work well. A touch of lemon juice can brighten it up even further.
• Sauce Gribiche: The key to a good Sauce Gribiche is balance. It should be tangy from the vinegar and mustard, rich from the yolks and oil, and full of texture from the pickles and herbs. Don't be afraid to adjust the ingredients to your taste. Some people like to add a touch of chopped celery or even a pinch of cayenne pepper.
• Serving: This dish can be served warm, at room temperature, or even chilled. It's a great appetizer or light lunch.
• Vegetarian/Vegan: The Sauce Gribiche, in its traditional form, is not vegetarian. To make a vegetarian version, replace the hard-boiled eggs with a creamy tahini or cashew-based dressing, adjusted for tang and seasoning.
• Make Ahead: The vinaigrette and Sauce Gribiche can be made ahead of time and stored in the refrigerator. The leeks are best cooked just before serving, but can be blanched ahead of time and kept in the refrigerator until needed. Be sure to let them come to room temperature before serving.
