Melvin's Barbecue in Mount Pleasant and James Island are famous for their legendary BBQ: pulled pork, ribs and more -- as well as their golden mustard sauce. In fact, Melvin's father, Joe Bessinger, may well be the person who invented mustard-based BBQ sauce in the 1930s in Holly Hill, SC. But their sides are just as noteworthy. Melvin's collard greens, for instance, are exceptional. Smoky with a slight sweetness, these collards will please even the pickiest of eaters.
