In case anyone's interested, there's a seller here in South Florida called 'The Mustard Factory.' They sell on-line as well as small shops hereabouts. I've heard the horseradish mustard is really good.
They have stores of their own, plus they are offered at some other shops. One of them is "Restoratives Cafe"! We NEED to meet there this November!
