Cooking pork spare ribs low and slow in the oven is an easy way of reproducing some of the conditions that pit masters have when they're making barbecued ribs, brisket and even whole animals.
Preheat the slow cooker to low. Slice each rib rack in half and set aside. In a large bowl, combine the ginger, garlic, spring onion whites, half the chilli, the soy sauce, miso paste and sesame oil.
