Wash the basil leaves thoroughly and dry them gently.

In your food processor, combine the basil, garlic, pine nuts, and Parmesan cheese. Pulse them a few times to break them down into smaller pieces.

Stop the processor and scrape down the sides. Add salt and pepper, then blend again until everything is well combined.
