Tips for serving with pasta: Before you drain your pasta, reserve some of the cooking liquid. That pasta cooking water contains starches that help attach the sauce to the pasta. Toss pasta and pesto with small splashes of the cooking water until you’re satisfied with the consistency.
Make it vegan: Omit the parmesan. Substitute 2 to 3 tablespoons nutritional yeast, to taste, or use vegan parmesan.
Recommended equipment: I like this Philips food processor (affiliate link). It’s affordable and does the job.
