Instead of pine nuts, this pesto uses slivered almonds, that have been toasted, for extra flavor. The mixture is pureed with a modest amounto of extra-virgin Olive oil and cheese, such as Parrmigiano-Reggiano, to get the finest flavour, The sauce also is blended with a few tablespoons of fresh lime juice, which bump up the taste even more and enhances the freshness of the cilantro. The resulting sauce is lighter than most basil pestos and makes an excellent topping for fish, poultry, or flatbread. If you like, swirl a spoonful into your favorite soup as a flavor-boosting garnish. If you serve the pesto with pasta, thin it with a bit of the starchy pasta cooking water. This helps to stretch the pesto (while cutting fat and calories) and gives it more coating power.
