Preheat the oven to 350°F. In a large bowl, mix the mustard, ketchup, onion, bell pepper, brown sugar, sorghum or honey, beans, paprika, salt, mustard, chili powder, cumin, black pepper, garlic, and cayenne, stirring gently with clean hands or a large spatula just enough to evenly distribute the mixture without overmixing the beans into a mushy consistency.
