We have two hazelnut trees in our yard, here in D.C. Usually, the squirrels get the entire crop, which is typically quite small. This year, however, there appears to be a bumper crop forming. A few green ones have fallen, cloaked in their frilly green wrappers, and many more could be shaken from the trees. We saw green hazelnuts that looked just like these, for sale in the Food Court at Harrod's when we were in London last August. We didn't find out how they were intended to be consumed, though. Does anyone out there know? I cut one of ours open, and it tasted slightly sour and astringent. Or should we just wait longer, risk more squirrel predation and see if they taste better?
