Here's probably my favorite Rib Recipe...
Baby Backs or Spare, I don't care.
I have this tupperwear deal that is designed for marinating and I can put just about 3 full sides of ribs in there. After I have skinned the ribs (pulled the membrane off the back of the ribs) I put on some cracked black pepper, slather with fresh garlic, and load them into the marinating deal. I then fill the marinator with apple cider and put it in the fridge overnight and go outside and soak down some apple chips/chunks.
The next day I prepare a dry rub with whatever I feel like putting in it. Usually granulated garlic, black pepper, white pepper, brown sugar, paprika, and chili powder. If I want to make them spicy I add red pepper and just a little dried mustard. Be careful with the mustard. A little goes a loooonnnngggg way. I can't give you specific amounts because I just go by feel not by a recipe.
Notice I haven't mentioned salt yet. I don't put salt into the marinade and I don't put it in the rub. I take a coarse salt and slather it on the ribs before I apply the rub. I also don't use garlic salt or onion salt. I want to know exactly how much salt I am going to use. Pull the ribs out, pat them dry, salt each side and apply
the rub liberally to both sides. Let the Ribs come up to room temp before you put them on the grill.
I load up the chimney with charcoal and newspaper to get a good amount of heat pretty quickly. I have an offset smoker so I put the charcoal in the fire box and add more coals on top.
I take my rib rack(s) and spray them with Pam (helps a TON when cleaning those dirty bastards later). Put the Rib Rack on the grill and put the ribs in it. Add wood chips or chunks (I usually use both), close the lid and

.
I adjust my vents and chimney until I get a good 225 degrees. I'm looking for a good amount of smoke coming out of the chimney. When the smoke dies down I add a few more briquettes and some more wood have a

and repeat.
The ribs closest to the hole to the fire box get done the fastest so I will rotate the ribs accordingly so that they get done at the same time. Also, I will put the rib tips that come with spare ribs right in front (prepared the exact same way as the ribs) of the hole to the fire box so they get done the fastest which myself and my guests will enjoy during the process. In my family we call these the nibblers. Nibblers go great with
When the meat starts pulling back away from the bones they are done. The end of the bones will start peaking through the meat. Also check the rigidity of the rack of ribs. When they don't flex very much they are done too.
The whole process takes about 3 hours.
If you want to add sauce I usually start with a base of regular mauls. I take a decent size pot and put it on the stove over medium heat. I throw in some olive oil and a bunch of garlic and let that sizzle for a couple of minutes. Then I add some sweet stuff like brown sugar, syrup, molasses, honey, white sugar, just whatever you have. Brown sugar and maple syrup are my two faves and I usually use both. Let that cook for a few minutes. Add a nice dark beer, let cook for a little longer, and then add the mauls. Cook that for a while (make sure you have a lid on this that is partially cocked so that it doesn't splatter but the steam can escape).
If I'm saucing them I will actually put more charcoal in my charcoal chimney and newspaper (not a ton), and start another fire. I will add those coals to the side I don't have the ribs on. I want the heat kicked up so the BBQ sauce caramelizes nicely. Once the temp of the grill exceeds 300 I will slather my ribs with sauce and close the lid for a few minutes. I will do this 2 or 3 times till the sauce is good and thick and caramelized. After that, yank the ribs and enjoy with a
