I purchased two racks of baby back ribs and would like to cook them for dinner. I put Raging River rub lightly on the ribs and put in the refrigerator about one hour ago. I plan to use Sweet Baby Rays Hickory & Brown Sugar sauce when cooking. Any ideas on what doam temp adn for how long. Also, should i put the sauce on the ribs before and during the cook. I have a rib rack to place the ribs on.
