An uncle of mine, who has just turned 90, recently compiled a list of uncultivated things he has gathered and eaten from the wild during his lifetime, and they amount to at least 32 different items. They include the aforementioned dandelion plus nettles, sorrel, bullace, damsons, sloes, winkles, cockles and rabbit plus 12 different fungi.
Add to this the 60 odd cultivated fruit and veg., plus goats milk, cheese, yoghurt etc. and the hen and goose eggs he acquired, he was the epitome of the 'good life' personified. I hope this tradition lives on.
