How to Make Memphis Style Ribs

1. Toast the fennel, coriander and cumin seeds in a sauté pan until fragrant and oils have been released. Grind in a spice grinder until in powder form. Feel free to use ground spices if you prefer, but use a 1/2 tsp LESS of each.
2. In a small bowl whisk together the toasted/ground spices and all remaining dry rub ingredients. Set aside. Whisk together the mop sauce ingredients. Set aside.
3. Peel membrane off from the back of ribs. Apply 3/4 of the dry rub all over both sides of the ribs. Reserve 1/4 of dry rub to apply before slicing after cooked.
4. Let sit for 30 minutes minimum (or 8 hours, covered and refrigerate overnight).

For Low and Slow:

1. Preheat gas grill or smoker to 225°F. Add smoker chips per manufacturer's instructions if using. Set up the grill for indirect grilling (See Note 3).
2. Place the racks, bone side down on the grill, close the lid. Let the ribs cook for about 4 to 5 hours for baby backs or 5 to 6 hours for spare ribs, brushing with mop sauce every 15 minutes.
3. Brush once more with mop sauce and remove from grill and sprinkle with one more round of the dry rub. Let rest 5 minutes. You're looking for an internal temperature of 195°F. Slice and serve immediately.

If short on time:

1. Preheat gas grill or smoker to 325°F. Add smoker chips per manufacturer's instructions if using. Set up the grill for indirect grilling (See Note 3).
2. Place the racks, bone side down on the grill, close the lid. Let the ribs cook for about 1 1/2 hours for baby backs and 2 hours for spare ribs, brushing with mop sauce every 15 minutes.
3. Brush once more with mop sauce and remove from grill and sprinkle with one more round of the dry rub. Let rest 5 minutes. You're looking for an internal temperature of 195°F. Slice and serve immediately.

For the Oven:

1. Preheat oven to 325°F.
2. Place the ribs, bone side down, on top of a wire rack set in an aluminum foil lined baking tray and bake for 2 1/2 to 3 hours for spare ribs or 1 1/2 to 2 hours for baby back ribs. Halfway through, cover ribs with aluminum foil to protect them from drying out. 
3. In the last hour of baking, baste the top of each rack with mop sauce every 15 minutes. At this point they should be tender enough to pull apart with your fingers. You want the ribs to have an internal temperature of 195°F. Sprinkle with one more round of the dry rub. Let rest 5 minutes. Slice and serve immediately.
