I finally had great success with ribs: They were super moist, with no foiling needed.
Here's what I did: Bought some loinbacks at Sam's Club, and for once, they were quite meaty! They come in 3-packs and I got one of the heaviest packs (8# total for 3 racks) ... maybe that's the key to getting meaty ribs, especially if the bones are the same size in all the packs.
So the stars were aligned to begin with.
Then I remembered reading a posting by Jack, a.k.a. Prison Chef, regarding a brisket question I had.
He said that there's a key to keeping meat moist: "... the one given in cooking is the higher the temp the lower the yield all other things being equal. by jumping your temps 11% you can expect your yield to be reduced around 5 to maybe 7%. or on a 14 pound packer excpect to come in around .35 of a pound lighter (around 5 ounces)."
He and others later described that the loss of yield was due to the loss of moisture in the meat. Basically, the higher the temp, the more moisture that "boils off the meat" just like boiling water evaporates into steam.
So I applied this logic to ribs. Instead of cooking ribs for 6 hours at 225*, as many people suggest, I tried 12 hours with the smoker dialed into 200*. (I've never checked my calibration at that temp, so judging by the time the ribs took to cook, the actual smoker temp probably was closer to 190* on avg.)
About an hour before taking them out, I sauced the ribs and put them back in to carmelize the sauce a bit.
The result: These were the most moist, best tasting ribs I've ever made. Surprisingly, they didn't pull back from the bone at all, which leads me to believe that the pulling back from the bone is caused by the meat drying out a bit and shrinking.
Anyway, for those of you who like moist ribs, try this super low and super slow method: set your smoker at 190-200* and check on them after about 6 hours (maybe check earlier if you are using babybacks). When they're almost done, add some sauce, put back in the smoker, and take out an hour later.
Try it and let us all know what you think of the results, and if that super low and super slow method results in a much more moist rib.
