Yellow mustard. Or really most any mustard. 

Once you go full mustard there is no turning back. 

Fun fact, Madison, WI has the worlds largest Mustard Museum. You can go there any day of the week and try out hundreds of mustards from around the world. They also ship via their website and have wonderful mustard gift packages. Visiting the mustard museum also makes for a perfect romantic date.  If she isn’t into mustard, then she isn’t worth your time.
