Kale has long been a popular vegetable in New England since it can be grown all year round in both the field and cold frames. Luckily, its popularity has really gained traction everywhere lately, giving us plenty of new ways to enjoy it – like this pesto pasta! Once basil fades like a summer memory, kale steps into the spotlight for its turn on center stage. Pesto, after all, just means sauce — it does not have to be made with basil. Elise already has a terrific recipe for kale pesto on this site, so I decided to come up with a slightly different variation to add to your repertoire. In this version, I use lacinato kale (also called dino or Tuscan kale) and blanch it to tame its bitterness and to bring out the sweetness that lingers under the surface. Blanching also helps the kale retain its bright green color. For extra creaminess, I used cashews instead of traditional pine nuts or almonds. They are sweet and buttery, and add richness to the pesto. Vegans could forgo the cheese and still end up with a delicious pesto to toss with pasta. If you have any pesto leftover, toss with potatoes, fill an omelet, or spread on a sandwich. I love how the earthy flavors of the kale pesto combine with whole wheat pasta. Once upon a time, whole wheat pasta tasted a lot like cardboard, but no more! Spaghetti, fettucine, bucatini and other forms of whole wheat, or whole grain, pasta would all work beautifully here. Pesto doesn’t have to be a distant summer memory – revive it with kale, a green that has real staying power! Add the kale to the boiling water and stir for 15 seconds, or until wilted and deep green. With a slotted spoon, transfer it to the bowl of ice water. (Alternatively, transfer to a colander and run it under cold water.) Reserve the cooking water in the pot. Squeeze the kale with your hands to remove excess water. With the motor running, pour in the olive oil. Add the salt and pepper. If needed, add water, 1 tablespoon at a time, to bring the pesto to the desired thickness. Taste the pesto and add additional salt and pepper if needed. Scoop out and set aside 1 cup of the pasta cooking water. Drain the pasta in a colander.
