A couple of months ago I watched a programme where the sprightly septuagenarian Angela Rippon skipped around the world looking for the secret of eternal youth. She found it on an island in Japan, where the average age of the inhabitants is about 150, and the secret ingredient in their diet is the purple sweet potato.
Rather disappointingly, not even Waitrose appeared to stock the purple sweet potato, only the bog-standard, non-life-expectancy-enhancing orange variety, so I was resigned to foregoing the chance of releasing my inner Peter Pan.
But that was before I went to the local supermarket in Siem Reap and discovered …
… the purple Pringle!
Not only is it the magic ingredient, but it’s cooked and packaged as a convenience food – what’s not to like?
My only issue now is how to get a lifetime’s supply shipped over to the UK. If anyone would like to go halves with me on renting a container ship, please let me know.
