Preheat grill on high. In a large bowl combine beef, pork, and chipotle cinnamon rub until ingredients are just evenly distributed. Form into 4 equal patties.
Grill each patty to desired doneness, topping with one slice of cheese per patty just before pulling from the grill. Toasted buttered buns until golden brown.
To build burgers, spread 1 tablespoon of mayonnaise on the crown of each bun. Spread 2 tablespoons of warm onion jam on the base. Place grilled burger on top of jam and two slices of candied bacon on top of the burger. Finish with the crown of the bun and serve with fries or chips.
