Kyle L,
The baby back ribs I purchase at Costco have had the membrane removed. I like that! Purchase plenty...cut into portions to suit......vacuum seal.....freeze. Take out of the freezer later to use, let thaw.....depending on portion maybe a day or two in the fridge section.
BRITU calls for 2 hours after applying the rub.................then cook.
You will like them...........cook until ribs reach at least 190 degrees. You have another thread about the lid thermometer........at least get a hand held digital thermometer from a kitchen gadget place in order to check the meat temps. Careful with the lid open time, ribs cool quickly and take a long time to get back to where you started.
For BRITU I put the ribs on a rack, large bone end down, cook three hours (no Peeking). After three flip end to end for another hour. In four hours doubt the ribs will be at 190 yet if holding the lid temp in the middle of smoke, experience will tell. Now that the most meaty part of the rib is up, a quick peek for meat temp (with hand held) about every 1/2 hour or so (depending on smoker temp). Others can tell by bending the rack of ribs, some stick a tooth pick into the rib. What ever works...........
Might take a try or two to get it down to a science.
