Yeah but a roll of biscuits where I'm from is a packet of hobnobs, which are already cooked when you buy them and would probably be called something like 'a stack of cookies' in your country.
So in the usa a roll of biscuits is the name for the raw dough in a cardboard cannister, that you portion and bake yourself, right?
And usa biscuits are kinda similar to english scones.
So is the packaging pressurised because the dough is yeasted/leavened? Or because of being packaged with a non oxygen gas as a preservative? I know you guys really like long shelf lives with your processed foods.
Would nitrogen be used? Or is carbonated dough a thing? And would that even work as a preservative or a leavening agent? Nah, thinking about it force carbonation in dough would be likely be bitter and have a really rank texture once baked.
Ok, so it's probably nitrogen or maybe bicarb? Would bicarb remain stable and unreacted in the dough for a full shelf life, and still work?
And I think usa biscuits are unlikely to be a yeasted, I remember usa folk on baking subreddits talking about only ever using yeast for bread and how they found it very weird and 'not normal' that yeast in cakes/non-bread baked goods is a thing in other places.

(No spoilers please, the fun bit of all this is in the figuring it out!)
Most of them barely speak english and think speaking another language means you're an illegal immigrant.
