Definitely when it comes to sloes, chestnuts, blackberries, hazelnuts, wild strawberries, elderflowers/berries, Wild Rose hips and mushrooms (though I am somewhat wary of these after poisoning us years ago when there was a glut on the farm).
I've tried nettles but not ground elder (inundated with it in my previous garden, I didn't know it was edible)
I've used various flower petals including sugaring rose petals and violets.
Are we repeating the "great depression" of the 1920's?
So Harry and family are coming back!
