All - I am going to make some mixed-green pesto this weekend with arugula, spinach, etc. I also have some brocoli rapini that is at the harvesting stage. In addition to the shoots I will eat, these plants have huge leaves around the exterior of the plant. If I put these into the pesto, will that work or will it be too bitter? I've not had rapini before, so not sure if there is any use for the outer leaves. I'm thinking if I mix them with the other greens and use garlic, cheese, etc. the bitterness will be cut enough. Thoughts?
