crisps probably don't come from the US on the crisps wikipedia page in the history section it says

The earliest known recipe for something similar to today's potato chips is in the English cook William Kitchiner's book The Cook's Oracle published in 1817, which was a bestseller in the United Kingdom and the United States. The 1822 edition's recipe for "Potatoes fried in Slices or Shavings" reads "peel large potatoes... cut them in shavings round and round, as you would peel a lemon; dry them well in a clean cloth, and fry them in lard or dripping".

...

Early recipes for potato chips in the US are found in Mary Randolph's Virginia House-Wife (1824) and in N.K.M. Lee's Cook's Own Book (1832), both of which explicitly cite Kitchiner.

A legend associates the creation of potato chips with Saratoga Springs, New York, decades later than the first recorded recipe.

I skipped a bit with another early recorded version that was also from a british book but that's it

I checked the book and it doesn't claim to have invented it it just presents it with all the other recipes but that could just be the style of cookbooks at the time I dunno I'm not a historian but eh proof enough that there's no evidence of them being american atleast and some evidence they're maybe british
