1/2 cup (2 oz/60 g) walnut pieces, pine nuts, almonds or pecans
garlic scapes to taste - at least two
2 cups (2 oz/60 g) packed arugula leaves
1/2 cup (2 oz/60 g) freshly grated Parmesan cheese
1 cup (8 fl oz/250 ml) extra-virgin olive oil
In a food processor, combine the walnuts, garlic, arugula, Parmesan, and 1 tsp salt and pulse to blend. With the machine running, pour in the olive oil through the food tube in a slow, steady stream and process until smooth, stopping to scrape down the sides of the bowl as needed. Taste and adjust the seasonings.
