Slow cooker method:
Cook, Auto/Low 8 hrs
Preheat the slow cooker, if required. Chop the rack into ribs and put them in the slow cooker. Season with salt and add the peppercorns. In a bowl, mix together all the marinade ingredients, add to the slow cooker, and turn the ribs to coat.
Cover the slow cooker with the lid and cook on auto/low for 8 hours. Remove the ribs from the slow cooker and serve with rice or on their own while piping hot. Garnish with the scallions.
Cook, 2-2 1/2 hrs
Put the rack of ribs in a large heavy-based pan and cover with water. Season with salt and add the peppercorns. Bring to a boil, then reduce to a simmer, partially cover with the lid, and cook for 1-1 1/2 hours until the meat starts to come away from the bone. Remove the ribs from the pan with tongs and set aside in a baking pan until they are cool enough to handle.
Preheat the oven to 325 degrees F. In a bowl, mix together all the marinade ingredients. Chop the rack into ribs and put them in a large Dutch oven. Pour the marinade over the ribs, turning them to coat. Cover with the lid and put in the oven for about 1 hour, keeping an eye on them to check they don't dry out completely - they may need turning in the marinade. Remove and serve with rice or on their own while piping hot. Garnish with the scallions.
