There's more than I know what to do with.
I started by watering the basil and allowing it dry on it's own. This makes the cleaning process a lot easier. Snip the tops off the basil plant. Rinse and lay out to dry. Pick off the leaves and compost the stems.
If you place the stems in water, they will root and grow more basil leaves. I jarred all the leaves and submerged them in olive oil. Displace all the air in the jar will olive oil. Storing it this way will keep it for winter use.
To make pesto, blend fresh basil leaves, garlic, parmesan cheese, salt, pine nuts and olive oil until it's at a consistency that you like.
