Ribs in 3

All you need to make mouth-watering baby back ribs are the ribs, of course, a bottle of purchased BBQ sauce and 3 hours at 300--so easy.  Slather the ribs with the sauce and put in the oven, covered.  Check each hour, turning and adding more sauce.  I served them with cornbread that I baked with a small can of chopped green chiles and about 1/2 cup corn.
