I’ll admit it; I’m biased about mustard.  There are some foods that can be so wonderfully complex, and mustard is one of them.  I’m a fan of complex food with variety in flavor.  I ordered some merchandise from the online store for gifts, and they included an obligatory catalog of the wonders of available mustard.  I haven’t yet been to the National Mustard Museum, but it’s certainly on my future travel itinerary.  (How great would a vacation based on good food experiences be?)
