Method

• Heat oven to 150C/130C fan/gas 2. Put the ribs in a roasting tin in a single layer and just cover with water. Cover with foil and cook for 1½ hrs. Drain well. If you are not finishing these straight away, cover and chill until ready to cook.
• Meanwhile, fry the onion in the oil in a pan until soft. Add the garlic, smoked paprika and chilli powder and fry for 1 min. Add the passata, purée, vinegar and sugar and bring everything to a simmer. Cook for 10 mins. If you are not using this sauce straight away, cool and chill.
• Heat oven to 220C/200C fan/gas 7. Brush the ribs all over with the sauce and lay on a baking sheet. Mix the potatoes with the oil, rosemary and seasoning in a large roasting tin. Roast for 40 mins on a middle shelf, with the ribs on the shelf above. Turn the ribs and potatoes halfway, until both are nicely browned all over. Tip the potatoes into a large bowl sprinkle with the vinegar and serve hot, warm or cold. Slice the ribs to serve and put any extra sauce into bowls for dipping.
