Remove leaves from stems and wash and spin basil leaves. Lay out on a tray and dab with paper towels to remove any excess water.
Toast pine nuts in the toaster oven for about 3 minutes, or just until beginning to brown. Set aside to cool.
Get out your handy dandy food processor and here we go!
Add basil, a handful at a time to a food processor. Pulse until pureed and continue to add remaining basil, until all basil is pureed.
Add the garlic clove and pine nuts and process again until smooth.
Finally, add Parmesan, salt, olive oil, and lemon juice and pulse for one last time! Refrigerate or freeze until ready to use.
