I dont use mustard much myself. The most i ever use is the base for a dry rub on pork. I like stuff like Grey Poupon mixed with mayo on a turkey sammich though. Jack Daniels used to offer a Southwest Mustard i really liked but they quit selling it. Plus it was way over priced.
INGREDIENTS:
VINEGAR, MUSTARD SEED, HORSERADISH, SUGAR, SALT, PEPPERS, CAYENNE PEPPER, SPICES, JACK DANIEL'S(R) TENNESSEE WHISKEY FLAVORING (NATURAL & ARTIFICIAL FLAVORS).
The only other thing i do like occasionally is a honey mustard type sauce for chicken nuggets/strips. That about all my brother likes too. Pops on the other hand loves all kinds of mustard. Not so much with peppers but he loves hot mustard or mustard with horseradish. Ive got several mustard powders including S&B which really has some zip to it, Colemans and a Dijon powder from myspicesage i got as a freebie. I think the only thing im missing atm is a white wine that is suitable but i do have a small bottle of Wild Turkey American Honey i use for cooking.
