Does anyone have a sauce that they use for pulled beef (chuck) sandwiches? I've been eyeing Jeff's pulled chuck recipe he sent around with some texas toast (and maybe some melted cheese) for a sandwich, but I was hoping to see if anyone has a recipe for a sauce. My initial thought was some mayo, horseradish, wash-your-sister sauce, garlic powder, onion powder, and maybe a touch of chipotle or cayenne powder for some zing. Any thoughts or recipe suggestions? Thanks in advance.
