Ribs: place the ribs membrane side up (whiter looking side) on a chopping board. Starting at one corner edge grab hold of the membrane then pull this up and off the back of the ribs. Discard the membrane.
Marinade: add the Worcestershire sauce, apple cider vinegar, garlic, ginger, cumin, salt and pepper to a glass jug and use a mini whisk to combine. Then set aside.
Individual ribs: use a sharp knife and working one rack at a time, cut the rack into individual ribs. Add these to a large mixing bowl as you go.
Marinate: pour the combined marinade over the chopped ribs and use a pair of kitchen tongs to toss and consistently coat. Then place cling wrap over the bowl and refrigerate up to overnight.
Preheat the oven: preheat the oven to 180°C / 350-375°F / Gas Mark 4-5. (This step is only needed 15 mins before the ribs go into the oven, so if marinating overnight, leave till the next day).
Oven bake: remove marinated ribs from the fridge, discard the cling film and transfer them into an oiled baking dish. Cover with aluminum foil and then place into a preheated oven on the middle shelf for 1 hour.
Honey barbecue sauce: add barbecue sauce and honey to a mixing jug and use a teaspoon to whisk together.
Rotate: after 1 hour use oven mits to remove the baking dish from the oven and place on a heatproof surface. Pull the foil off and use kitchen tongs to rotate each rib to the other side. Put the foil back over the top of the baking dish and place the ribs back into the oven for another hour.
Grill/broil: change the oven setting to grill at 200°C 392°F6. Remove the ribs from the oven, place on a heatproof surface and discard the foil. Let the dish sit for 2 to 3 minutes. Then use kitchen tongs to transfer each cooked rib to a silicon mat on a baking tray. Use a pastry brush to brush the combined honey barbecue sauce over each rib, including the sides. Then place the ribs into the oven on the top shelf. Grill them for 10 minutes, then remove and re-baste. Return the ribs to the oven for another 10 minutes of grill time.
Serve: once grilled remove the ribs from the oven and place the tray onto a heatproof surface. Let them sit for at least 2 minutes. Then use kitchen tongs to transfer them to a serving dish. Provide leftover honey barbecue sauce for dunking.
