Have you ever heard of a bang-bang? It's been around for a couple of years yet it seems underappreciated. Huh? What do you think a bang-bang is? Is it something that Donald Trump has practiced and said? Maybe, but get your mind out of the gutter, this is a food blog. Is it a new boy band? Nope, but I guarantee that it will be now. Is it a noise that comes from a gun or a car? Nope. Well, it could be but not the bang-bang, I'm talking about. Is it this?
