The message
from Bruce contains these words:

Cotherstone (or is it Cotherston, I can never remember) made in
Durham, is an interesting cheese, although it's not always easy to get.


Is that another blue? Can't say I have ever come across it.

White, reasonably firm, not crumbly. Made with unpasteurised milk on a
farm in, surprise, Cotherstone (with an "e"). If your local
cheese-monger has heard of it, keep supporting him/her, because they
know about cheese - but if they offer to get it for you, ask them if
they know how far it is to Barnard Castle... Alternatively, divert from
your usual route back from Lancashire and call at the Cheese Shop in
Northgate Street in Chester - they often have it in stock(and they drive
over to Cotherstone to get it).
