Pistachios, almonds, and walnuts or even seeds like sunflower, sesame, and pumpkin can replace the traditional pine nuts in pesto. Pretty much any edible nut tastes delicious—just make sure to toast and cool the nut before grinding them into the sauce.
What You’ll Need To Make Pesto Sauce
Traditional pesto is made with garlic, nuts, salt, basil leaves, Parmigiano-Reggiano, and extra-virgin olive oil. It’s important to use top-quality ingredients, as the flavors really shine through.
For the cheese, be sure to use authentic Parmigiano-Reggiano from Italy; domestic Parmesan is not the same thing. You can always tell if the cheese is authentic by looking at the rind, which is embossed with the name over and over. If the cheese is already grated, it should be labeled “Parmigiano-Reggiano,” not “Parmesan.”
For the nuts, I use walnuts instead of the more traditional pine nuts for a few reasons. First, I always seem to have walnuts in the house (pine nuts can be very pricey). Second, in recent years an increasing number of people, including me, have fallen prey to a bizarre problem with pine nuts called Pine Mouth Syndrome, a bitter, metallic taste in the mouth that develops a day or two after eating pine nuts. It can last for weeks and make eating or drinking anything very unpleasant. (You can use pecans or almonds, too.)
To begin, combine the walnuts and garlic in the bowl of a food processor and pulse until coarsely chopped.
Add the basil leaves, salt, and pepper.
Process until finely chopped.
Then, with the food processor running, add the olive oil through the feed tube in a steady stream.
Process again until smooth, and that’s your pesto sauce.
