The middle number, as you probably know, is the time in foil. I have not foiled ribs for a number of years. I smoke baby loin back ribs exclusively. I buy the Swifts Premium from Costco. They are very meaty, as there is a good amount of the loin meat still attached. There are 3 racks to a Cryovac and the membrane is already removed. I smoke them naked for about 3 hours at 260-275* until I get a good bend. Then I sauce/glaze them twice for 15 minutes each time. I let them rest for 30 minutes, slice and serve. They are very tender, great taste and have a slight tug.
Give that method a try. I hope you like it, Joe. :grilling_smilie:
