1. Preheat the oven to 400F. 2. Mix cumin, coriander, pepper and chillies with the oil and butter. 3. Peel the potatoes, carrots and parsnips and cut into chunks, or halve lengthways. 4. Put in a roasting tin large enough to take them in a single layer. 5. Pour the spice mixture over the vegetables and toss everything together until well coated. 6. Roast for about 1 hour until golden and crisp, turning the vegetables a couple of times during cooking so they brown evenly. 7. Sprinkle with sea salt and serve. ---------------------------------------------------------------------------
