Step 1

Heat the oven to 170°C/fan150°C/ gas 3½. Rub a little oil on the ribs, then sprinkle with the sugar, mustard powder, garlic salt, paprika and some black pepper. Put a roasting rack in a large roasting tin and pour in 350ml water. Put the ribs on the rack and cover with foil. Roast for 2-3 hours until very tender.

Step 2

Heat the barbecue. Brush the ribs generously with the barbecue glaze. When the coals are white, grill for 4-5 minutes on each side until blackened and sticky. (Or, to finish in the oven, brush with the glaze and cook at 220°C/fan200°C/gas 7 for 10 minutes or until glazed and sticky.)
