Remove silver skin from bone side of ribs. Never used to do this, but now understand why the pros do. Using the tine of a dinner fork helps get things started, then it just peels off.
Put a large sheet of foil on the counter and place the ribs meat side down. You want enough foil to VERY lightly wrap (or tent) the ribs for grilling.
All the spice measurements above are estimates. We like things a bit on the zippy side, but not burning hot -- just a little bite. With that said, we season the bone side of the ribs heavy with garlic powder, medium heavy with cayenne, medium heavy with pepper, and light with salt. Really hard to over do it, as after 4+ hours on the grill, the spices seem to mellow.
Flip the ribs and repeat the seasoning. Again, may look heavy, but the flavors kinda vanish during cooking. Why you need to try it once and adjust to taste the 2nd time. I never taste the garlic no matter how much I put on, but the cayenne does adjust the spiciness. Even when we go pretty heavy with the cayenne, it is not over-powering.
Lightly wrap the ribs. You want to create a tent on top so the foil does not touch the meat. Pull up the ends lightly and seal. You do want to seal things so moisture does not escape. You can put these in the fridge all day, or put on the grill immediately.
I have a Weber Genesis gas grill that has a front, center and rear burner. Don't have to pre-heat, but I only turn on the front burner to low-medium -- grill will heat to about 250 degrees. Place the ribs towards the rear of the grill (away from the burner). Leave them there for 2 hours. Nothing you need to do except make sure the temp stays around 250. 200 is fine, 300 is fine -- but lower seems to produce better results.
After 2 hours, open the foil and coat with BBQ sauce. Should be a lot of juice in the foil at this point. If not, add some water, beer, or something. Re-seal the foil and let them go another 2 hours.
Now the tricky part. Pull the ribs towards the front the grill. Get a couple wide spatulas, open the foil, and carefully lift the rack of ribs from the foil and place directly on the center of the grill. At this point, the ribs will be pretty much done. Remove the foil from the grill. Turn on all the burners and coat the ribs with Deercamp BBQ sauce. Close the lid. Things should start smoking from the sauce dripping and burning. If things are not smoking, turn up the heat. Keep an eye on things at this point. You do want a nice char, but you don't want to overdo it. Maybe 10-20 minutes for this step.
Get the 2 spatulas and remove to a cookie sheet or platter. Enjoy.
If you like Deercamp BBQ sauce, you will like these. Fall off the bone every single time, and they require very little effort or attention. You can adjust the base seasoning to your liking. I have made these with the same general recipe and process from anywhere between 3 hours and 6 hours with very little loss in outcome. Hence the reason I call it "no fail".
