Pesto comes from Liguria, a region in the North of Italy. It is most commonly used as a sauce for pasta but there are many other ways to add pesto. Spread pesto on some crusty bread, mix it with ricotta to make a creamy dip, use as a marinade for meat and fish. You can also add other herbs such as mint and parsley or use macadamia nuts instead of pine nuts. A very diverse sauce that is quick and easy to make.
In a food processor place the basil leaves, garlic and pine nuts. Whizz to combine, then add the cheese, whizz again. With the motor running add the olive oil. When combined add the sea salt to taste. Store in a plastic container with a drizzle of oil on top.
