I have been buying these huge bunches of basil for $.99. I use about half of it before it starts to wilt. So, I'm making pesto with the remainders. I'm making up the recipe from what I seem to recall my ex-step-grandmother made it with.
A large amount of fresh pesto
a large chunk of high quality parmigiana cheese (or asiago cheese)
high quality ex. virgin olive oil
garlic -I used pre-chopped because fresh tends to get very over powering if uncooked.
Throw it all in a blender or food processor. I used My baby food maker, which I guess is really just a small blender. Blend until it looks like pesto.
This is goooood. Really good. I'm going to freeze half of it.
