Will the famed cheddar cheese one day be replaced with rows of avocado? I think I can remember when I first saw an avocado. Perhaps the late eighties, or early nineties. It was when they first arrived in Safeways supermarket in Inverness. My mum (who grew up in the tropics) was excited because before then, it was not possible to get such things in the north of scotland. In fact, according to some, any kind of green vegetables were pretty much frowned upon; a pragmatic approach to no-nonsense eating without which we could never have been UK leaders in the fields of heart disease and low life expectancy. Sad to see Iceland now leading its Brixton customers similarly astray.
