Meheh, I sell cheese for a living.
Aye, the Lanark Blue. Made in Lanarkshire (about halfway between Embra and Weegie land, and a bit south) by a bloke called Humphrey Errington (who I've met).
It's sort of like Roquefort, but far, far superior. Also give the Dunsyre Blue a whirl, another damn fine cheese. More like Gorganzola though.
See, I'm a bastard. I've got you all interested in one of my favourite cheeses, and certainly my favourite blue, and now you realy want to try it. Trouble is, it's made from ewe's milk. Ewe's only give milk at certain times, and right now is not one of them. Lanark Blue is well and truely out of season, and impossible to get.
