Pesto Mayonnaise:
1 cup (packed) fresh basil leaves (about 2 ounces)
1/3 cup lightly toasted pine nuts
1 tablespoon minced garlic
1/2 teaspoon salt
1/4 teaspoon freshly ground black pepper
1/4 cup extra-virgin olive oil
1/4 cup freshly grated Parmesan
1/4 cup mayonnaise (good quality store bought, or homemade)
In the bowl of a food processor or blender, combine the basil, pine nuts, garlic, salt, and pepper and puree, scraping down the sides as needed. With the machine running, add the oil through the feed tube and process until the mixture is thick and smooth. Add the Parmesan and process for 15 seconds.
Transfer to a bowl and add the mayonnaise, stirring to blend well. Cover tightly and refrigerate until ready to serve. (The pesto mayonnaise will keep for 3 days refrigerated.)
Yield: 3/4 cup
