There was very little for me to do since the rub was already made. But you do need to start 24 hours before grilling.
First the membrane on the back of the ribs needs to be removed. Learning from Martha Stewart, I make a starting cut, then use a paper towel to grab the membrane and just peel it off. Then I rubbed the mix over the entire rack of ribs.
Either place the ribs in a plastic bag or place on a rimmed sheet and cover with plastic, and place in the refrigerator overnight.
When ready to grill, preheat the gas grill to medium (about 350 Fahrenheit). Double wrap the ribs in foil and place on direct heat on the grill. Lower the cover and grill for 25 minutes, turn, and grill for 25 minutes more.
Remove from the grill and test its tenderness by using a fork between the ribs. It should be fall apart tender. If not, rewrap and grill for 10 minutes more.
Take the ribs off the grill and let rest for 10 minutes. (Alternatively, you can unwrap them and place back on the grill for a couple of minutes one each side to crisp them up.)
Slice the ribs.
And if you like, drizzle some BBQ sauce over them. We like our local Wabash BBQ sauce.
