I'm obsessed by the crispy outer leaves you get when you roast Brussels sprouts.

Those sound amazing! I usually just roast my brussel sprouts with butter, onion, bacon, salt and pepper.
Have you eaten kale chips? Do they take on a similar texture to those?
I made kale chips once awhile ago. I don't remember them that well but I know I wasn't wowed; I suspect my own cooking is to blame. I think the Brussels sprouts chips are much more thin and delicate and much tastier.
