- 200g/7oz vegetable oil
- 450g/1lb raw potatoes, peeled, cut into cubes
- 1 tbsp coriander seeds, toasted in a dry frying pan, crushed to a powder
- 1 tbsp cumin seeds, toasted in a dry frying pan, crushed to a powder
- 1 tbsp garam masala
- 1 tsp ground ginger
- 2 garlic cloves, peeled, crushed to a paste with the edge of a knife
- 3 red chillies, finely chopped
- salt and freshly ground black pepper
- 200g/7oz boiled potatoes, mashed until smooth
- 100g/3½oz plain flour
- small bunch fresh coriander
- small bunch fresh mint leaves
- 1 tsp sea salt
- 75ml/2žfl oz white wine vinegar
- 200ml/7fl oz plain yoghurt
- Preheat the oven to 180C/350F/Gas 4.
- For the potato cakes, heat half of the oil in a casserole in the oven. When the oil is smoking, add the raw potato cubes and turn them until coated in the oil on all sides.
- Stir in the spices, garlic and chilli to coat the potatoes, then season, to taste, with salt and freshly ground black pepper.
- Roast the potatoes in the oven for 20-25 minutes, or until crisp and golden-brown but tender inside. Remove the potatoes from the casserole using a slotted spoon and set aside on kitchen paper to drain and cool slightly, then mix into the mashed potatoes.
- Shape the mashed potato mixture into twenty to twenty-four 5cm/2in patties, using your hands.
- Sprinkle the flour onto a plate and season, to taste, with salt and freshly ground black pepper. Roll each patty in the seasoned flour.
- Heat the remaining oil in a frying pan over a medium heat. Add the patties, in batches, and fry in the oil for 2-3 minutes on each side, or until crisp and golden-brown on both sides and heated through. Remove from the pan using a slotted spoon and set aside to drain on kitchen paper. Repeat the process with the remaining patties.
- Meanwhile, for the sauce, blend the herbs, salt and vinegar in a food processor until well combined. Stir in the yoghurt.
- To serve, divide the Bombay potato cakes equally among six to eight serving plates. Place dipping bowls of the sauce alongside each.
