RE: Pringles officially NOT a potato snack
The Pringles formula for the UK is slightly different. The US version does not have corn flour (starch?) Here is the page listing ingredients for UK's Original Flavor Pringles:
Dehydrated potatoes, vegetable oil, vegetable fat, corn flour, wheat starch, maltodextrin, emulsifier: E 471, salt, rice flour,and dextrose.
Most of the 'real' British chips (they call them crisps) are really quite good.
