Serves 2 as a main or 4 as an appetizer
Kosher salt or fleur de sel
2 scallions, white and light green parts separated and finely sliced
1 tsp [5 ml] red wine vinegar
2 hard boiled eggs, peeled
1 tsp [5 ml] Dijon mustard
1/3 cup [80 ml] extra-virgin olive oil
1 tbsp [15 ml] capers, rinsed and dried
Pinch dried chili flakes
2 tbsp [30 ml] handful of fresh, flat leaf parsley leaves, chopped
1 lb [450 g] asparagus, peeled if needed, trimmed and cooked to your liking
In a small bowl, pinch together 1/4 tsp [1.25 ml] salt with the white part of the sliced scallions. Once the scallion begins to release some juice, stir in the red wine vinegar and set aside.
Separate the egg yolks from the hard boiled eggs. Place one egg yolk in a medium bowl. Chop the other egg yolk and egg whites separately, and keep both aside for later.
Mix the Dijon mustard into whole egg yolk until smooth. Using the back of a spoon or fork, beat in 1/3 cup of the olive oil in a thin, steady stream. Once emulsified, stir in the vinegar and white scallions.
Add the reserved egg whites to the sauce, along with the capers, the chili flakes and most of the parsley. Taste and season with salt and pepper as needed. If the sauce seems too thick, loosen with the extra olive oil.
To serve, arrange the cooked asparagus on a plate. Spoon over the sauce, then garnish with the chopped egg yolk, reserved parsley and scallion greens.
Note: This asparagus makes a fine tartine topping (as pictured). If desired, toast two large slices of whole wheat sourdough bread, then top with the asparagus and the hard-boiled egg vinaigrette.
