- 2 large handfuls of good-looking radish leaves, stems removed
- 30 grams (1 ounce) hard cheese, such as pecorino or parmesan, grated or shaved using a vegetable peeler
- 30 grams (1 ounce) nuts, such as pistachios, almonds, or pinenuts (avoid walnuts, which make the end result too bitter in my opinion)
- 1 clove garlic, germ removed, cut in four
- a short ribbon of lemon zest cut thinly from an organic lemon with a vegetable peeler (optional)
- 2 tablespoons olive oil, plus more to get the consistency you like
- salt, pepper, ground chili pepper
Put all the ingredients in a food processor or blender or mini-chopper, and process in short pulses until smooth. You will likely have to scrape down the sides of the bowl once or twice. This produces a thick pesto; add more oil and pulse again to get the consistency you prefer. (This can also be done with a mortar and pestle; it’s great for your karma and your triceps.)
Taste, adjust the seasoning, and pack into an airtight container (glass jar is good). Use within a few days (it will keep longer if you pour a thin layer of oil on the surface) or freeze.
Thin it out as needed to flavor polenta, to line the crust of vegetable tarts, to garnish sandwiches and tartines, to rub a rack of lamb, and to stuff oven-roasted fish.
