Place the pine nuts in a dry skillet over medium heat to toast, shaking the pan to keep them moving, until golden brown and fragrant. Transfer the toasted pine nuts to a food processor.
Add all the remaining ingredients, except the Parmesan cheese, to the food processor, and pulse in short bursts for 2 minutes to finely grate the pine nuts and combine everything into a sauce.
Add the Parmesan cheese to the food processor, and pulse for 15 more seconds, just to combine. Serve immediately, or refrigerate until ready to use.
HELPFUL TIP: Pine nuts can usually be found in a small packet in the baking section of your grocery store. Walnuts or blanched almonds can be used in place of the pine nuts (you should still toast them in step 1); however, the pine nuts really give pesto its classic flavor.
