Serve pesto on fresh pasta, spread on a halved baguette and broiled, or as a pizza topping. This recipe calls for basil, but you can experiment with other herbs such as parsley, thyme, tarragon, and cilantro. If you’re a garlic fan, feel free to use more.
In a blender or food processor, combine garlic, basil, nuts, salt, pepper, and half of the oil. Puree, then slowly add remaining oil. If using immediately, stir in Parmesan; if not, freeze mixture in a resealable plastic bag, squeezing out any air. (Pesto turns brown when exposed to air.) Add Parmesan before serving.
