Food & Cooking Recipes Avocado Cream Sauce Close Credit: Chris Simpson Total Time: 10 mins Yield: Makes about 1 1/4 cups Avocado is puréed with sour cream and lemon juice until smooth and creamy for this easy, irresistible sauce. The acid found in the sour cream and the lemon will prevent it from browning too soon so you can make it as much as three days ahead. Serve alongside seafood and vegetables for dipping, like in our recipe for Grilled-Shrimp Grand Aioli. Directions Combine avocado, sour cream, lemon juice, oil, and 2 tablespoons water in a food processor or blender; purée until smooth. Season with salt and pepper. Refrigerate in an airtight container until ready to serve, or up to 3 days.
