We love mustard on YumSugar. Party admits to sometimes eating it with a spoon, and I even make my own.

So what might seem like a silly national day of observance has us pretty excited: this Saturday, Aug. 1, is National Mustard Day. Don't forget to celebrate by slathering some of the yellow stuff on your sandwich, hot dog, or anything else that suits your fancy. But first, see how much you know about this condiment by giving my quiz a squeeze.
