Pesto

Pesto is an Italian sauce, generally attributed to Northern Italy, specifically the city of Genoa. It is believed that this sauce was developed as a way to store excess basil at the end of the season. It is based upon basil and olive oil and usually also has parmesan cheese, garlic, and pine nuts, but there are many variations upon the recipe. It has many uses, it can be put on pasta or on bread or be used to flavour meats or pizza, however, this sauce should be used sparingly, as consuming too much olive oil for those not used to it can cause mild illness. See the talk page for more information.
