Step 1

Pulse basil and pine nuts in a food processor: Place the basil leaves and pine nuts into the bowl of a food processor and pulse a several times.

Step 2

Add the garlic and cheese: Add the garlic and Parmesan or Romano cheese and pulse several times more. Scrape down the sides of the food processor with a rubber spatula.

Step 3

Stream in the olive oil: While the food processor is running, slowly add the olive oil in a steady small stream. Adding the olive oil slowly, while the processor is running, will help it emulsify and help keep the olive oil from separating. Occasionally stop to scrape down the sides of the food processor.
