This homemade farfalle pairs well with pesto. To make the pesto: Pulse 4 cups fresh basil, 1/3 cup toasted pine nuts, 1 small garlic clove and 1/2 teaspoon salt in a food processor until coarsely ground. With the machine running, drizzle in 1/3 cup olive oil and puree until the pesto is mostly smooth. Stir in 1/4 cup grated Parmesan.
