i like wrapping them in foil brushed with a SMALL bit of liquid smoke, and apple juice and coated with a dry rub. 300 degrees for 2 to 2 and a half hours. check them at about two hours. then toss them on the grill with some sauce to get them charred up a bit. you can do them a bit early and let them cool so they dont fall apart too much on the grill. which should be cleaned and oiled a bit so they dont stick.
or you can braise them, rub them with your favorite seasoning, place them meat side down and overlapping in a roasting pan. add a cup or two of of liquid. beer, juice, or water. place some lemon slices on the back of the ribs. cover and braise until fully cooked and the bones can almost be pulled. 300 to 325 for 2 to 3 hours depending on the type of ribs and amount.
