3-3/4 oz. (5 cups packed) fresh basil leaves
1/4 oz. (1/4 cup) pine nuts
1 large clove garlic, peeled
Kosher salt and freshly ground black pepper
1/2 cup extra-virgin olive oil; more for storing
1 oz. grated Parmigiano-Reggiano (1/2 cup from a box grater; 1 cup from a rasp grater)
Pulse the basil, pine nuts, garlic, 1/2 tsp. salt, and 1/8 tsp. pepper in a food processor until finely chopped. With the motor running, slowly pour the olive oil into the feed tube and process, stopping to scrape the sides of the bowl as needed, until the mixture forms a thick paste. Transfer to a medium bowl and stir in the Parmigiano. Season to taste with more salt and pepper.
