Preheat the oven to 275 degrees F.

Line a baking sheet with foil, enough to fold over the ribs, approximately twice the size of the baking sheet.

In a small mixing bowl, combine the sugar, paprika, salt, chile powder, cumin, garlic powder and cinnamon.

Place the ribs on the prepared baking sheet. Generously sprinkle the ribs on both sides with the spice mixture. Really rub it in! (I wore plastic kitchen disposable gloves)

Place the ribs meat-side down and fold the foil tightly around the ribs to make a sealed packet. Bake the ribs until they become pliable but not falling apart, 2 to 2 1/2 hours. You know the ribs are done when the meat pulls away from the bone. Keep the ribs wrapped in the foil to keep warm.

When you are ready to serve, fire up your grill and char them. You can also slather the ribs with some tangy BBQ sauce and char them on the grill, basting them with the sauce and turning as they char up.

Serve the ribs with extra BBQ sauce on the side.
