I am sure that the following won't be a surprise to anyone on this forum, but it will almost certainly horrify most people in our 'pampered' society!
Whilst tidying up the kitchen and rotating tins, on Friday, I found a number of cans that are/were passed their sell-by date (in the range of 2008 to 2011). Naturally, I have been eating the contents, which are still 'fresh' and show no signs of deterioration (and I suspect, will still be 'fresh' in another five years).
Obviously, I have followed the golden rules when storing tins: no dented cans and store in a cool, dry place.
