Spicy brown mustard on everything that is good with mustard. Inglehoffer! This brand is the greatest, but it's a tad expensive. Boar's Head is a nice alternative. Usually I wind up with Gulden's because it's what I grew up with, and it's cheaper.

I'll eat yellow, and it's not like its bad, but it's not the same. It's like eating a Hershey bar vs. eating some gourmet chocolate.
