It is necessary to make small batches of this dressing because the avocado will discolor slightly on the second day; however, it is so good and so versatile, that it probably won’t last that long anyway. We have found that using Champagne vinegar adds zest without the harshness associated with other types of vinegars. For a tasty and unusual touch, serve the dressing over cooked chilled vegetables, such as fresh asparagus or artichokes.

Ingredients

• 1 ripe avocado, peeled, seed removed, and cut into quarters

• 2 tablespoons Champagne vinegar

• 1/4 cup water

• 1/2 cup unflavored low-fat yogurt or sour cream

• 2 tablespoons cilantro

• 1/4 teaspoon salt

• 1 teaspoon sugar

• 1 clove garlic

• 1 fresh serrano chile, seeds and stem removed

Instructions

Place all of the ingredients in a blender or food processor and blend until thoroughly mixed. If the dressing seems too thick, add more water or yogurt. Use as soon as possible; store, covered tightly in the refrigerator until ready to use.
