Much like wine, a favorite cheese depends upon the situation...
A nice Gouda or Munster is an excellent cheese for everyday use.
I really like using Gruyere in omelets.
Mimolette is a really neat cheese that I use with an endive tarte.
Then there's Epoisses which is a killer stinky cheese.
Leyden is a really tasty cheese from Holland that's been aged with cumin.
I now need to head to the refrigerator...
