I wish you well with that, but honestly there's a reason that down here in mustard sauce territory you'll almost never see a mustard sauce come across the table. The reason is that the sauce makes such a strong impression, people either HATE it or LOVE it. Too much polarization of judges. Play to the center my friend.
By the way, I'd never have a party and not have 2 (yes, minimum of 2) different mustard sauces. Some family and friends love it. Save it for the at home use.
