Homemade Pesto
One key to perfect pesto is chopping all the ingredients by hand, preferably with a sharp mezzaluna or knife. This pesto will keep a bit in the refrigerator, but it really hits its peak when served soon after it is made. The technique here is: chop a bit, add some ingredients, chop some more. I think part of the reason she does it this way, instead of chopping everything all at once, is because some things get chopped into oblivion. Other ingredients, not as much. It encourages a spectrum of cut sizes throughout the pesto contributing to the overall texture. All told, the chopping took me a leisurely twenty to thirty minutes, I wasn't in any particular rush. You'll also notice this recipe doesn't have any added salt (just the saltiness from the cheese), make sure your pasta water is well salted if you are going to use this pesto on pasta. If you skip it the overall flavor profile will fall flat. Also, be sure to adjust for seasoning before serving. With food this simple, you need to get the seasoning right. Trust your tastebuds.
