Okay guys,
Quite a lot of conflicting information so still a bit unsure. Thanks for taking the time to help so far.
Anyway to help get a positive id, I went back tonight to get some more info for you. See Attached pics. There were around 4 or 5 trees on the edge of old woodland. On checking the size of the trees, one of them I would estimate at 50ft tall. Others are more like 25-30ft.
I am primarily interested in making jam from these, but understandly want to be on the safe side. Don't want Cyanide poisoning or anything ?
Cheers,
Craig
