I have no idea if they are poisonous, but I'm not dead
They ARE incredibly winky until cooked so that may be why I'm not dead as they are too gross to eat many of raw.
Please people don't take the stupid things I do as fact that it is safe for you to do also. I am that eejit who will try something if she's fairly sure it'll be ok.
For example I was only told last year that you should cook beech mast
apparently it's no good for you raw.... I shall let you know in a few years what the damage is long term cos I've et loads of the stuff
