Pesto isn't just for basil, though traditionally that's what pesto is made of. The word pesto itself means "pounded" in Italian. Famous in Genoa, the pesto of basil, pine nuts, Parmesan and olive oil is a delicious sauce on pasta. But many herbs and/or greens can take the place of basil to create a flavorful pesto. In the past I've made it with parsley, cilantro and even ramp greens. This time I've made a pesto from radish greens.
It may sound crazy but I love using up every last remnant of vegetables. It's not unlike saving vegetables scraps for stock. I mean why throw anything away when it's good for flavor? Radish leaves are not only on the radish for show, they're very much edible as a pesto or even sautéed and tossed with pasta. They offer up a unique fresh and peppery flavor that enlivens the palate.
The next time you buy a bunch of radishes, save the greens and use them—you'll be pleasantly surprised. Try the pesto spread on sandwiches, mixed into pasta, or used as a sauce on pizza in place of tomato sauce.
