Ingredients
1/4 cup plus 2 teaspoons lemon juice (2 lemons)
2 avocados, preferably Hass, halved lengthwise and pitted
2 red grapefruit
3/4 teaspoon coarse salt
2 tablespoons chopped fresh tarragon, plus more for garnish
Freshly ground pepper
1/4 cup olive oil
Lime wedges, for serving
Preparation
Brush 2 teaspoons lemon juice over flesh of avocados; set aside.
Remove peel and pith from grapefruit using a sharp paring knife. Working over a medium bowl to catch the juice, carefully carve out segments from between membranes. Transfer grapefruit segments to a small bowl; set aside. Reserve juice in bowl.
Add 1/4 cup lemon juice, the salt, and tarragon to the grapefruit juice; season with pepper. Whisk in oil in a slow, steady stream. Add grapefruit sections; toss gently just to coat.
Place each avocado half on a plate. Top with grapefruit mixture, dividing evenly. Garnish with tarragon. Serve with lime wedges.
