Back to the original topic. There are all manner of ways to cook ribs. The minion method, 3-2-1, 8+ hours over something like 200 degrees. I've done them all. Hell, I've got a website dedicated to the art and science of grilling. Here's my go to method for Baby Back Ribs (BBRs) which are my favorite rib. That's just a preference thing. If you go with Spares then add a little time to this method if they are thick, but no more than 30 minutes or so. If they are thin, then keep the same time, but always watch the ribs to let you know when they are done, rather than relying on time. This isn't baking, this is grilling and there are a lot more factors than just setting a temp and a timer. Some grills run hotter, or colder, or take longer to heat back up when you open them up to baste, spritz, sauce, add fuel or wood, etc. I'll get to letting the ribs tell you when they are done in a minute. First, peal the membrane off on the back. The first couple times you do this it will seem ridiculously hard. After you do it a few times it will be ridiculously easy. Paper towels are your friend here. Use a fork, butter knife, chopstick to get under the membrane then grab with paper towels for grip. Once you master it you won't need the fork or chopstick. I hesitate to give this advice because I don't want people to rely on it too much as a few successful practice rounds is all it takes to be able to peal the membrane with ease, but I will give it anyway. If you can't peal the membrane back, then score the back of the ribs (bone side) repeately with a sharp knife in a couple different directions. Score it really good. Now that the membrane is pealed back )or scored) what to do with the ribs? Myself, I do this a day out and put them in a ziplock with apple cider, garlic and black and white pepper. I leave them in the marinade for 12 hours or more. You can use whatever you like here. I've used Jerk Sauce,
Walkers Wood being my fave, as a marinade. I've used Peach and Pepper sauce. Whatever you want. My dad skips the marinade, applies the rub the night before and wraps in seran wrap. That's fine. Try them all. PRactice is the best part of all this!! The next day I remove the ribs from the marinade, pat dry with paper towels, apply some course salt, black and white pepper to each side of the meat and apply a rub.
Always apply rubs/salts/pepper, to the bone side down first. Seems like it shouldn't matter, but if you do meat side first and then flip to the bone side, all the rub/salt/pepper touching the cutting board is going to stick to the board and not the meat requiring you to reapply your rub. The bones keep the boneside from touching the cutting board as the bones are bowed up. It's a simple thing but it will save you a lot on the rub. Now to the grill. I set up the grill for indirect grilling, coals/smoke wood (or burners and smoke wood) on one side, meat on the other. I do mine at 275-300 for 2 hours. That's it. Other than moving the ribs around a bit to get the ones closest to the fire farther away and vice versa (if necessary) I don't do anything except add more fuel if the fire looks like it's dying and smoke wood if the smoke ebbs. The result is just short of fall off the bone (FOTB) ribs every time. I feel ribs should be tender, but firm and not FOTB. People request FOTB all the time and I make them by simply adding 30 minutes to the process and some foil. At the 1 hour 15 to 30 mark, I pull the ribs, place them bone side down on a large sheet of foil and turn up the sides. I add a little (like half a cup) of fluid which can be cider, beer, wine, bourbon, whatever, and seal it up and place it on the indirect side for 30-45 minutes. You can also add more rub here if you like. Then I remove from the foil, back on the indirect side to fim up what will be sort of mealy rub from the moisture. Don't bother with any smoke wood now as it won't have any impact. Another option is to slather the meat side of each slab with any of honey/syrup/molasses and more rub if you like, and put in the foil. They won't be overly sweet as you might expect but they will be incredible. I mentioned watching the meat and here is what I mean. When the meat pulls back from the bone a quarter to half inch they are done like this:

Some ribs will be done with less pull back if they have lower fat content. That's when you need to let the elasticity of the ribs talk to you. Pick them up with the tongs. When they are raw they fold in half. When they are done they don't give all that much. When you see ribs like those above, pick them up and get a feel for the elasticity so you will know in the future in case you get ribs that are lower in fat and don't pull back as much. Now, people are going to say that I'm nuts doing ribs for only 2 hours. They will say the only way to do ribs is to do like 6 hours of smoke to have them come out well. I've met those people. Those people waste expensive smoke wood for 4 hours and mock me for going so short. I mock them for running the cost up on smoke wood, but I digress. Ribs only take on smoke for at the most 3 hours and that's only if you have the temp at like 190. The reason for long cooking times is more for breaking down tough connective tissue than it is for the smoke. Ribs are tender enough on their own. And if they are only going to take smoke for 2 hours then why prolong the process unless you are doing so to increase the social aspect of grilling? I have no problem with that, but I have a problem with the scoffers that say 2 hours isn't long enough. To them I show them one picture. Not that picture of the ribs above, but of the those same ribs above sliced:

Look at that rib on the right and tell me it would be possible to have a deeper smoke ring. Two hours of smoke and the rings almost touch in the thinner part of the rib. I suppose it's possible if they cold smoked them like salmon, but that's a different process altogether... I teach Ribs 101 to all of my buddies and might be doing so at a local culinary school soon. Ribs aren't all that hard. A little practice and some knowledge is all you need. Also a willingness to ignore those that are so set in their ways as to how they do theirs to realize there may be a better way.... Trust me, if I find a better way I will discard this method in a heartbeat.
