In a shallow baking pan with a lip place ribs in a single layer fattiest side up and rub the sweet and smoky dry rub for ribs on all sides.
Cover the pan tightly with tin foil and bake for 2 hours.
Remove the baking tray carefully from the oven as there will be liquid in the bottom. Check that the ribs are becoming tender. If they are still tough, re cover them and put them back in for another 15 -25 minutes.
Remove the ribs to a plate and drain the pan of all liquid. Place the ribs back on the tray and brush both sides with BBQ sauce.
Turn the oven down to 275 °Bake for 60 minutes uncovered or until ribs are tender and pull apart with a fork.
Remove ribs from the oven and baste the ribs again with BBQ sauce.
