Ingredients

3 large eggs 

1 tablespoon white-wine or Champagne vinegar 

1 tablespoon country-style Dijon mustard 

3/4 teaspoon sugar 

1/4 cup extra-virgin olive oil, plus more for drizzling 

2 tablespoons capers, drained and coarsely chopped 

2 tablespoons finely chopped small cornichons (about 6) 

2 teaspoons fresh thyme leaves 

Kosher salt and freshly ground pepper 

1 pound asparagus, trimmed 

Preparation

Prepare an ice-water bath. Bring a small pot of water to a simmer over medium heat. Lower eggs into water; cook 9 minutes. Transfer to ice bath; let stand until cool enough to handle. Peel and slice into rounds.

Whisk together vinegar, mustard, and sugar. Slowly whisk in oil, then capers, cornichons, and thyme. Season to taste.

Preheat a grill or grill pan to medium-high. Drizzle asparagus lightly with oil and season with salt and pepper. Grill, turning once, until crisp-tender and charred in places, 3 to 4 minutes. Transfer to a platter, top with eggs, and spoon vinaigrette over top; serve.
