Preheat your oven to 300⁰. Combine the spices and brown sugar together, then rub all over the ribs. Wrap the ribs tightly in tin foil, then place on a baking sheet. Slowly roast the ribs for 2 - 2 ½ hours.
2. Step
While the ribs cook, make your maple bbq sauce. In a sauce pot, heat the olive oil over medium low heat. Add the onions and garlic and sweat for 8-10 minutes, or until softened and translucent. Add the ketchup, worcestershire, vinegar, syrup, salt, and water. Bring the sauce up to a gentle boil, then reduce to a low simmer for 35 minutes, or until the sauce has darkened and thickened.
3. Step
When the ribs are done, remove and unwrap the foil. To finish, grill the ribs on medium heat for 3-4 minutes per side, while brushing on the sauce to slightly caramelize. Serve with additional sauce on the side.
