Mmm - not sure, to be honest. I like them both equally, but it depends on my mood. And, for me, it has to be Cheddar. I think I am the only person I know who used to take huge slabs of Cheddar cheese with me to France when we went there on holiday. I loved the bread, but it had to have some nice tasty Cheddar on it. At the start of the holiday I would generously allow the rest of the family some of my cheese, but by the end I was eeking it out!
