* I eyeball the basil – 4 cups is about 4 large handfuls. This ended up being enough to fill a 64 ounce Vitamix container (semi-packed).
* Depending on how you like your pesto, you can use half basil and half Italian flat leaf parsley.
* If you’re serving the pesto immediately, add the Parmigiano-Reggiano cheese to the pesto and blend.
