Mustard based carolina BBQ sauce in the Chicago area.

I was in Racine Wisconsin, and remembering how some people had requested this awful stuff (I had the severe misfortune of living in Charleston and never liked it). Anyway, saw "Carolina Gold" mustard based sauce in several flavors.

If they are in Racine at a butcher shop, they should be available in Chicagoland as well.

Lillie Q's excellent carolina gold sauce is available for purchase at the restaurant, along with the rest of their sauces.
