Leyden is a cow's milk cheese from the Netherlands, similar to Gouda with a very firm, light yellow interior which has been flavored with cumin seed. Leyden cheese can also be made with caraway seed. This cheese would traditionally be served with dark beer and crusty dark bread but its sharp flavor pairs equally well with a nice Shiraz. For your cheeseboard add onions, mustard, and crackers.
