In a large saucepan bring the water to a boil. Season boiling water with 2 tablespoons garlic, 4 tablespoons Cajun seasoning and 4 tablespoons seasoned salt. Boil ribs in seasoned water for 15 to 20 minutes.
In a bowl mix together barbecue sauce, 2 tablespoons garlic, 2 tablespoons Cajun seasoning, 2 tablespoons seasoned salt and Worcestershire sauce.
Place ribs in large baking trays and apply a generous amount of the barbecue sauce mixture to the ribs. Set aside for 10 to 15 minutes to marinate.
BBQ the ribs for 7 to 12 minutes per side, until nicely browned.
