The trick I learned so they cook MUCH faster is:
Season them, pour on your favorite sauce, place in microwavable/ovenproof casserole dish, with sides high enough for the pan drippings. Cover with wax paper and microwave on high for 5 minutes till cooked halfway.
Flip ribs over. Baste with more sauce & the pan drippings. Cover with foil instead of the wax paper. Transfer to a preheated oven and bake the rest of the way at 375-400° till they fall off the bone - about 45 minutes. Baste with more sauce & pan drippings a couple times throughout baking. Yum!
EDITTED TO ADD: A tip I learned from Tyler Florence on the Food Channel is that it is the slow heat AT THE END that makes it fall off the bone. As you are cooking, for a while, the muscle seizes up & becomes tough. When you keep cooking
beyond that point, the muscle relaxes again, until it finally falls apart & off the bone. So if the ribs or any meat is still too tough, keep cooking!
People make the mistake of cooking at the end, with too high heat, & not long enough. If your heat is low enough, you can almost never OVER-cook meat.
