On a cutting board, sprinkle 1/4 teaspoon salt over garlic and roughly chop. Using a flat side of the knife blade, crush mixture into a thick paste. Add to a food processor with pine nuts, basil, and 1 tablespoon oil. Pulse until ingredients are finely chopped. With machine running, add remaining oil in a slow, steady stream. Add Parmesan and pulse to combine. Season with salt and pepper.
Use walnuts or pecans for the pine nuts. You can also replace half the basil with arugula or parsley. Or try cilantro along with pumpkin seeds.
