I have a question about the ingredient ". 1 bunch of cavolo nero" on the recipe "ceci bean stew with cavolo nero & herb dusted crouton " from frankieolives.
It's a variety of kale - a lot of times you can swap out other kale varieties though, if they are easier to come by!
It's also commonly called dinosaur kale or lacinato kale in the grocery store.
...or sometimes black kale. The good thing is that it is becoming easier to find these days.
