Tangy pesto of kale, capers, garlic, and Parmesan. Perfect to add to pastas, salad dressings, or use as a spread on a grilled cheese sandwich.
Pesto is generally made by grinding garlic, a pinch of salt, and pine nuts together with a mortar and pestle until a creamy paste forms. Some people say the salt is added later, but I say no to this. The salt draws out the liquid of the garlic and helps to break it down into the paste you want. An herb is added, frequently basil thanks to the Genoese, followed by more pounding, rubbing, and scraping by the pestle (which likely lent its name to the pesto). Next comes grated hard cheese, like a salty Parmigiano Reggiano, pecorino romano, or a Grana Padano. A few glugs of extra virgin olive oil brings it all together - and preserves it.
What a lovely way to connect to food, watching it transform in small bowl under your own efforts, pungent garlic, basil, and cheese seducing the senses. And a nice little upper-arm exercise thrown in as a bonus.
But I didn't do that, if only because I didn't have time that day. And I didn't have any basil.
But I had lots of kale in my garden. So I switched kale in for the basil pesto, and traded seduction in for the speed of my food processor. It's not the same experience, I won't argue that it is, but it was done in five minutes. And some days, that's all the time I have.
This is a great pesto to have in the refrigerator - it keeps for about a week or more as long as it's covered with a little slick of oil. It might last longer, but it was gone way before then. By the time I threw it into eggs and pasta, and on top of breakfast pizzas , I had just enough to spread on some crackers.
