Re: New SmokerHowdy, Ron, and welcome to our group!
First of all, congratulations on the new addition to the family! I've owned the same model GOSM for a couple years, and I can tell you that you are in for some real good times as you grow into this hobby.
It sounds like you did a very nice job for your first time. I suggest that you read through the threads that describe the 3-2-1 method for ribs. I won't go into it too deeply here, since it is explained in great detail in other areas of this forum. Basically, 3-2-1 means 3 hours in the smoker bone side down unwrapped. Spray or mop every 45-60 minutes. Next, wrap in HD foil with a splash of apple juice and place back in smoker for 2 hours. Last hour, unwrapped. Voila! Moist, tender, fall-off-the-bone ribs!This method is practically foolproof.
Okay. That takes care of that. Now, the real secret to rib perfection lies in the preparation and the rub. First and most importantly, the remove the thin membrane from the inner curved surface of your rack. It doesn't matter whether you're using baby backs or spare ribs, the membrane MUST be removed. The reason for this is that during the cooking process, this membrane will inhibit smoke penetration and it also becomes very tough and rubbery, resulting in a tough, chewey and less flavorful rib.
Secondly, apply a thin coat of plain yellow mustard all over the meat prior to applying the rub. Don't worry, the mustard flavor will cook out over the long smoke. The mustard is important beacause it helps the rub adhere to the meat better and as it cooks it helps to form the ever coveted "bark" that imparts so much wonderful flavor.
Finally, the rub. This is where you control your destiny! There are many rubs available commercially and most are pretty good. I however, prefer to make my own because I have better control over the heat/sweet/salt. You will find a variety of free recipes right here in this forum that are quite good. So experiment to your hearts content! I will suggest that you give Jeff's Naked Rib Rub a try. It is very well worth the small fee. The ingredients are simple and easily acquired in any local grocery, and its very easy to modify to your own personal tastes.
Thats about it, in a nutshell. Have fun. Good luck with your next endeavor and don't forget to post your results. 8)
