Ingredients

1 small clove garlic, peeled and smashed

Coarse salt and freshly ground pepper

1 avocado (8 ounces), chopped

1 tablespoon white-wine vinegar

1 cup low-fat buttermilk

1 teaspoon Dijon mustard

2 tablespoons extra-virgin olive oil

1 cup mixed fresh herbs (such as chives, tarragon, basil, cilantro, and parsley), plus more for serving

Crudites, for serving

Preparation

Using a flat side of a knife, mash garlic with 1/2 teaspoon salt until a paste forms. Transfer to a food processor with avocado, vinegar, buttermilk, mustard, oil, 1/2 teaspoon salt, and 1/4 teaspoon pepper; puree until smooth. Add herbs; pulse just to combine.

Transfer to a bowl, cover, and refrigerate at least 30 minutes and up to 4 hours. Sprinkle with more herbs and serve, with crudites.
