I have tried many recipes for ribs. I buy the cheapest and fix them this way and they are so tender, they fall off the bone. Sounds to simple, but try.
I put a rack of ribs in a pan and put whatever seasoning on them you like. Cover them with foil and bake in a 200 degree oven for about 3 hrs. I then uncover them and put barbarcue sauce on them and either put them on the grill for a short time or put them back in oven on broil for a few minutes. You will surely be surprised.
