Having originated in Genoa, Italy around the 16th century, Pesto comes from the Genoese word Pestâ, meaning to pound or crush. The name refers to the traditional blend by mortar and pestle of crushed garlic, basil, coarse salt, European pine nuts, Parmigiano Reggiano and olive oil. Commonly accompanying pasta, it can also be found in springtime versions of Genoese minestrone. Tradition noted, we’ve made a few adaptations. Pasta has been replaced by low-carb zucchini noodles, European pine nuts by antioxidant-rich, locally-sourced walnuts, and we added a zing of lemon zest for a little flair. I love this dish in the late summer/early autumn when zucchini, basil and tomatoes are in abundance.
