I got this tip from Cooking Pleasures Magazine, and it made some awesome ribs yesterday in about 1 1/2 hours
1. Rub your baby backs with a sugar-less spice rub (I like BBQ of America from Penzey's)
2. Toothpick them in a circle (so they look like a Crown Roast)
3. BBQ them standing up, covered for 30 minutes. Then flip them onto the other side and cover and grill for another 30. They should be almost done at this point.
4. Un-pin and lay flat, saucing with sauce, for another 15 minutes or until done.
The easiest, quickest ones we have ever made!
