Here's how it went with our first Baby Back Ribs on the Quantum. Used rub from allrecipes.com link provided by jc. Bought some hickory chips, and per CB, did not soak them. To be honest, we are somewhat disappointed because we had difficulty keeping a constant 250-275 temperature (we used the CB Memphos Dry recipe). We used indirect method, bone side down. At low it would fall to around 200, if we turned it up a notch, it was up to 300, then back down a little, etc. Kind of a pain to have to keep watching those gauges. The rub was a little salty, I thought and the ribs were not crusty on the outside, just dry and a little tough, but tender and moist inside. I think this is totally the result of them taking two hours to cook at a temperature that was too low – outside conditions were not a factor – there was no breeze and it was warm. They did not fall off the bone, but were not difficult to get off the bone, either. At the very end, my DH flipped them to direct and upped it to 500 for not more than 5 minutes. That’s about the only time we got any actual smoke from the wood chips. I think next time, if we try indirect again, we will try cooking them for a shorter time at around 300 on the indirect side and see what happens.
