Take one slab of Baby Back Ribs and sprinkle generously with your favorite rib rub. I like to use a combination of seasoning salt, garlic powder, and sage.
Cut the ribs into three even portions. On the back of the ribs, scrape the membrane with a knife diagonally each way, three times. In a deep pan place 1 cup of water and 1/4 cup of liquid smoke. Place the ribs vertically in the pan. Cover with HEAVY DUTY foil and place in a preheated 275° oven. Cook for five hours. Pull ribs out of the oven and try to pull a center bone out of the center rib. If it comes out clean, they are done. If it does not come out clean, place back in the oven for 30 more minutes and try again. Continue until the bone comes out clean. Then wrap the ribs in foil and place in the refrigerator. They will hold for three days.
