THERE is an ongoing debate about the merit of - and differences between - best before and use by dates for food.
It makes me smile a bit. My generation is perhaps the last that knows the taste of rancid butter, for instance.
Being brought up in an era when not everyone had a fridge, you learned to rely on your eyes, taste buds and general common sense to know when something was past its best.
Butter, bought loose, came with no sell-by date, and would be kept on the go in the larder until it simply betrayed its demise by its taste.
Mould on cheese? Just cut it off.
You may remember me telling you about the beautifully-tiled entrance to one of the Buttercup Dairy shops being still visible in Dean Road.
The dairy had its origins in Scotland.
A historian of the company, Bill Scott, has now placed a video on YouTube – which tells the Buttercup Dairy story and features lovely pictures of some of the old shops.
