Here's the crazy thing - the pickles only require 4" of the scallion. Granted, 4" is the majority of the part that's normally consumed, but I didn't really love the idea of letting any more of these go to waste than necessary. Another quick search brought me Clagett Farm's roasted lemon and scallion pesto. I barely looked at the recipe, but I did make something like it out of my "waste." It's pretty radically different from the green pestos that I've had, but it has a lot of promise. My plan is to toss it with some chicken and linguine for dinner tonight, after I finish the pickles and assemble the cat's Fortress of Solitude.
What I should have done with the waste's waste was to toss it into the freezer in preparation for making stock, which should be done before too long. Next go.
