Pringles

Pringles are one good chip. How do you think they make them? Do you think they mash potatoes up and then spread the mash on some sort of curved thing-y before baking them? Really think about this. They can't just slice them off of a roll of some kind because of the curve. There has to be more to it than that. And do you think they add the flavors like sour cream & onion or BBQ to the mash batter? Or do you think they bake regular Pringles and sprinkle the flavors on afterward?
