I gave up on commercial rubs long ago, they are all just too salty!
My rub is SO simple it's pathetic! But good!
Mix together equal parts Cinnamon, Curry Powder, Cayenne Pepper. That's IT!
I pull the membrane off the back of my baby back ribs, in the middle of the back of the slab work your fingers under the membrane, lift and pull it off and discard. At this point I sprinkle my ribs with dried and crushed up African Blue Basil, an herb that you can grow that gives a sweet flavor and fragrance to ribs, but if you don't have any, that's fine.
Sprinkle the rub on both sides and the bone ends of the ribs, cook at 325F on a grill or smoker until a toothpick slides easily between the bones, turn heat back and slather with Sweet Baby Ray's BBQ sauce, let cook another 20-30 mins until sauce thickens and caramelizes, Slice and serve!!!
