If I can't find it in my little podunk grocery store I don't use it. If you need mustard to hold on the rub your using to much rub. I usually unwrap the piece of piggy and plunk him on the grate & slam the door sometimes I use a little salt( being a NC boy you should know how good that is) and once in a while I use a little of a made up rub or the combo I stated earlier. I save the mustard for hot dawgs & cheeseburgers

Probably as many rub recipes as there are members here... LOL
