As the photos - shared exclusively with New Ideas Food - show, the cake doesn't have any visible mould and the cream filling still seems ‘edible’.
Says Colin: ‘I have a Coles pink Swiss Roll in my cupboard which was put there as an experiment about 10 years ago now and still looks pink and edible!
‘Put in the cupboard on 16 October, 2010. It’s faded a little due to being exposed to the light and has some damage from being knocked about. No mould at all though.’
But while the Swiss Roll appears to be ‘soft and spongy’, Colin confirms that looks can be deceiving.
‘The Swiss Roll still looks edible but not even Coles could create a culinary delight that’s soft and spongy at time of purchase, but which doesn’t become brittle when kept in a cupboard for almost 10 years,’ he says. ‘No mould, but it is no longer spongy to my dismay.’
Colin marked the beginning of the experiment by writing the time and date on a piece of paper, before tucking the cake away in his cupboard.
‘We just did it as an experiment,’ he explains.
New Idea Food has contacted Coles for comment.
