Thanks to all for the rib advice. Cooked 6 full racks of baby backs using the 3/2/1 method at 250* w/ inverted platesetter, drip pan and rib rack. Rubbed with salt/pepper before the cook. Sprayed the ribs w/ apple juice before each flip. Coated w/ hoisin bbq twice in last hour. Absolutely delicious and fall off the bone tender. Sauce was a big hit as well. Hoisin bbq sauce ingredients: 1/2 cup hoisin, 3 Tb. soy sauce, 3 Tb. sake (rice wine), 2 Tb. sugar, 2 Tb. ketchup, 2 Tb. minced garlic.
