Have you ever met a Florentine? Of the cookie variety, I mean. With an identity that is half cookie, half confection, and totally nutty, they're well worth getting to know.
I wrote a great primer on Florentines, including an accessible and delicious recipe, which you can find on the Craftsy blog. I really highly suggest that you check it out, because these things are interesting, probably unlike most cookies you bake, and crack-addictive.
