Firstly, I'm going to have to preface this with a whole explanation to avoid the crisp-chip / chip-fry confusion. Basically it can be explained thus: What the Americans call "Chips," the British call "Crisps;" and what the British call "Chips," the Americans call "Fries." (For more scientific information, see my own research at More's Uncyclopaedia, the world's (mis)leading database of facts, figures, lists, and general trivia.)
Being British, I am inclined to use the words God gave us and not the more common, colonial / international corruptions. I assume this stance will not offend anyone.
Now, clearly they are not purely chip-flavoured – they are the flavour of chips dipped in a mustardy sauce, but still. Really, are you so obsessed as a nation that when offered the chance to have ANY flavour in the world, you chose that your potato-based snack should taste like a different potato-based snack? I sometimes wonder if the ultimate Dutch snack would be a crisp that tastes like a chip dipped in mashed potato and sprinkled with flaked potato skins. Mmm, starchy.
