Back to the bread or crackers bit.

Blues or a soft ones like Brie don't usually work too well on bread for me.

I recently found that I liked the combination of Danish Blue on Ryvita but, more generally, I think the plain old cream cracker is as good as anything. I'm not a fan of the "biscuits for cheese" type boxes I sometimes see at Christmas. Most of their contents detract from the taste of the cheese.
