There was an article in the Daily Telegraph today about how foods past their 'best before' dates are entirely usable, even when they are several years after their 'best before' date.
There are companes who buy food that is past its 'best before' dates and then sell it on, both safely and legally to consumers.
I am like silverlining, everything gets eaten. menus get replanned, food is frozen, raw, part processed or ready to eat. If I have food waste to recycle, it is bacon rinds, fish skins or chop bones.
Prices were quoted as low as 1p for a jar of Heinz mustard and 9p for a jar of Waitrose cook-in sauce. with 'best before' dates of 2019 and 2020.
Best before' is very different to 'use by' dates and it is illegal to sell those.
I would give a link, but the DT hides behind a paywall
