As Amelie constantly likes to remind me... I'm a perfumed ponce... therefore I love root vegetable crisps... beetroot, carrot, sweet potato but especially parsnip
However I am a fair-minded chap & can see good in both maize & potato:
Maize:
Space Raiders - the best value that 10p can buy (aside from a Freddo Frog) & one that has beaten off all advances of time & inflation.... Space Raiders will still be 10p in the year 2367
Probably eaten by real Space raiders too...
Wotsits - the cheesey daddy - nuff said
French peanut / monkeynut maize things... only found in the land of snail eaters but v v v moreish.....
Worcs Sauce French Fries - the living bollocks
& sadly rare as chuff now
Tomato Wheat Crunchies - OK not strictly maize but then not a spud either.... n v nice...
Potato
Walkers C&O - an all time classic
McCoys Sweet Chili Chicken.... lusssssssssssh
Walkers Sweet Chili - inspired....
but the number one king of crisp crown must go to (imo)
Kettle Cracked Black Pepper & Crushed Sea Salt...
Minimal, simple & yet sublime.....
