I'm going to nominate a mature cheddar-like cheese, made from unpasteurised milk, called Lincolnshire Poacher and made by a friend of a friend. I think it's available all over the country now. Yum :o)

Gjetost for me - Norwegian goats milk cheese.

I think a mature creamy Stilton takes a lot of beating.

pennylopie] sounds scrumptious! French cheeses are simply out of this world... my personal favs are St. Nectaire, St. Emilion, and roquefort. Hmmm, I think I'll stop by a fromagerie and boulangerie on the way home tonight and pick up an nice Sancerre rouge while I'm at it!
