It's a great day for Basil!
Here is the approximate recipe for hand chopped fresh Pesto.

Mince two or more garlic cloves. it al depends on the freshness of your garlic and how much of a garlic flavor you want
I chop all of the basil that I've picked
 Mix well. add Salt to taste. pour in enough Olive oil to make it just a little soupy. I add a minor amount of Parmesan cheese after I add the olive oil. What you don't eat can be kept in the fridge for over a week.

1-2 cups of Basil
about a cup of Walnuts, Pecans, Pine nuts, or even almonds work too
2-4 cloves of Garlic
salt to taste
About 2 cups of olive oil
1/4 cup Parmesan cheese
