AGREEDWelcome to SMF glad you joined us. You can place them directly on the grates personally the only time I use rib racks is if I'm trying to smoke more than will lay on the racks.
im new to smoking meats.... Can i put ribs(baby,country,spare) straight on the grate of the smoker or do i need a rib rack? is there any benefit to either, and is the cooking method the same? thanks
