In this version, I use walnuts instead of pine nuts because I always have them on hand and they are packed with nutrients and omega-3 oils. Adding a bit of lemon juice gives this pesto a slight citrus note and keeps it from turning brown. I also found adding parsley to the mix helps retain that vibrant green color, as basil oxidizes quickly once broken down.
You'll also need a food processor for this recipe.
This pesto is on the thicker side and not super oily, so if using as a pasta sauce you need to ladle in some of the pasta cooking water to thin the sauce before tossing the pasta in it.
Using young tender basil leaves produces a nicer flavored pesto.
Pesto is one of those things that really doesn't rely on exact measurements, so this is more of a guideline than an exact recipe.
It's easy to add too much oil, so be watchful and add it very slowly, to the point of almost dripping it in.
