This classic uncooked sauce made with fresh basil, garlic, toasted pine nuts, Parmesan or Pecorino cheese and olive oil originated in Genoa, Italy. A versatile sauce that is used on a variety of dishes, especially those with pasta. Nowadays "pestos" are made with ingredients such as cilantro and mint.

2 tablespoons pine nuts (pignoli)

2 cups lightly packed fresh basil leaves

1 cup (4 ounces) freshly grated Parmesan or pecorino cheese

1/4 cup extra virgin olive oil
