Pesto derives its name from the mortar and pestle traditionally used to make this Italian paste. In this case, mint has been added to the traditional recipe.
To prepare the pesto, place the mint, basil, grated Parmesan, garlic and pine nuts in a blender or food processor with half the oil and work to a smooth paste. With the machine running, add the remaining oil in a thin, steady stream. Draw a vegetable peeler across the piece of Parmesan to make thin curls and set aside.
