Ingredients
Oops! Something went wrong. Our team is working on it.
4 cloves garlic, peeled
¼ teaspoon kosher salt
1 large bunch fresh basil (about 4 to 5 ounces)
3 tablespoons pine nuts
2 ounces finely grated Parmigiano-Reggiano cheese
½ cup mild extra-virgin olive oil
Directions
Crush garlic and pinch of kosher salt in a mortar with the pestle until garlic is mashed and paste-like, 1 or 2 minutes. Add basil in 3 or 4 additions, crushing and pounding down the leaves until they form a fairly fine paste, about 8 minutes or more depending on size of leaves and thickness of stems. Add and pound in pine nuts.
Transfer a handful of grated cheese to mortar and pound into the sauce. Add another handful of cheese and incorporate into the mixture. Continue adding cheese a handful at a time until completely incorporated, about 5 minutes.
Drizzle in olive oil 1 tablespoon at a time, pounding it into the sauce. When all the olive oil has been added and emulsified into the mixture, transfer pesto to a bowl and drizzle the surface with olive oil.
Chef’s Notes
Use a microplane to finely grate the Parmigiano-Reggiano cheese. Two ounces should yield about 1 1/2 cups of unpacked grated cheese.
Of course, you can play around with the ratios of the five ingredients and easily adjust this to your taste, but no matter how they're combined, taking the time to crush them by hand is well worth the effort.
