You may laugh, but an old friend was once offered some from a bag we were sharing. Having obviously never stumbled across these exotic treats before, he shoved a handful, unshelled, into his mouth. Not wanting to seem like a village idiot, he manned up and chomped down the lot (with much grimacing), saying: ''Nah, bruv, it's just how I eat 'em''. I made sure to offer him a second handful which was similarly demolished with bravado (but less gusto). I don't remember a warning on the bag though.
