Preheat the oven to 220°C. Grease a roasting pan.
1. Mix the currants and vinegar in a small bowl. Set aside until needed.
2. Place the whole cauliflower head and olives in the roasting pan. Season with the paprika, cumin, salt and pepper. Drizzle 45ml (3T) of the olive oil over the cauliflower. Roast for 45 minutes. Cover to prevent burning and cook for a further 45 minutes or until tender.
