Seasoned with the sweet-heat of Jamaican Jerk - a blend of peppers, thyme and tropical spices, including cinnamon and allspice - these ribs never last long once they are on the table.

Brown ribs, in batches, in hot oil in large ovenproof Dutch oven on medium-high heat. Return ribs to pan; add beef stock and orange juice. Bring to boil. Remove from heat; cover tightly with foil
Bake 1 hour and 30 minutes. Remove ribs with slotted spoon, reserving drippings in pan
Stir rum, brown sugar and remaining 1 teaspoon Jamaican jerk seasoning into reserved drippings. Bring to boil. Reduce heat to low; simmer 10 minutes, stirring constantly
Mix 3 tablespoons of the sauce and remaining 2 tablespoons flour in small bowl with wire whisk until smooth. Add to sauce in pan; cook 2 to 3 minutes or until slightly thickened, whisking constantly. Serve sauce with ribs
