Well, an update on the Ribs that I made Here.
I was going to make them again and didn't have St. Louis or Baby Back, so I tried spare ribs for the first time. With spare ribs, you must let them cook longer than the St. Louis or Baby Back. Lesson learned the hard way for me as the ribs were not done enough to fall off the bone.
Another thing I tried was to crisp them up a bit. After they have slow cooked and are wonderfully tender, put them in the oven and broil them on low for about 5-10 minutes per side. Just cook them enough so they get nice and crispy on the outside (if you like that) and so tender and juicy on the inside.
