Add the garlic cloves and pine nuts to the bowl of a food processor, blend until finely ground.
Scrape down the sides of the bowl and add the carrot tops and salt. Pulse until the carrot tops are finely chopped.
With the processor running, slowly drizzle in the olive oil and lemon juice. Process until smooth.
Stir in the Parmesan cheese.
Eat right away, store in an airtight container in the fridge, or freeze in ice cube trays for later use.
