An Italian sauce made of fresh basil leaves, fresh garlic, pine nuts, olive oil, Pecorino and Parmesan cheese and salt. The word "pesto" originates from the word "pestle" which means ground or pounded, since the ingredients were ground in a stone or marble bowl called a mortar, and pounded with a wood or stone rod, which is a pestle. Pesto, or "pesto alla genovese," originated in Genoa in the area called Liguria.

Add to a food processor or blender and blend until thick.
