Confused to report that today's weird impulse grocery buy, this thing, is absolutely the experience of eating just the interior of a candy bar. As if someone set out to answer "what if you had a Snickers bar that was only the structurally-unsound nougat in the middle, flying free?" It's not nougat, it's sesame-based and much more crumbly, but spiritually... lucky for me I find that's the best part of candy, so la creatura's 404 on the first bite was quickly followed by gobbling the whole thing down.
(Having broken into one I can explain the "marble": it's got a teeeensy bit of chocolate marbled through it. Only a tiny bit though! I could barely see it; I did not taste it.)
