Who’s picked a blackberry this year? The rest of the time brambles are regarded as weeds and are the source of many a scratched shin, but at this time of year they give something back, a bountiful provision of glossy black fruit. If you just pick the ones at waist height, there should be plenty left for nimble mice and birds to find out of human reach.
Other options for foraging include elderberries (amazing flavour in jams or crumbles), wild strawberries, the blackberry’s more genteel cousin the raspberry, apples, sloes, damsons, beech nuts (get them before the squirrels do) and hazelnuts. You can even try a giant puffball fungus but they have to be new, smooth on the outside and white all the way through.
Things to bear in mind when foraging:
For me there is something really satisfying about walking in the countryside with a handful of fresh berries to browse on. Why not tap into your hunter-gatherer?... well at least the gatherer part.
