Mix the yogurt, ginger, garlic, spices, tomato purée and lemon juice in a bowl. Pull the outer leaves off the cauliflower, trim off the very bottom of the stalk, then cut into 8-12 wedges, 3-4cm thick. Blanch in a pan of simmering water for 3 mins. Drain, then leave to dry before tipping into a large bowl. Mix with the marinade, cover and leave in the fridge overnight.

Make the chutney by blitzing all the ingredients in a blender or food processor until smooth. Loosen with 2-3 tbsp water if it seems too thick.

Put the cauliflower directly on the barbecue grill. Cook for 7-10 mins on each side or until nicely charred and you can pierce the stalk easily. Alternatively, cook in a griddle pan, turning, over a high heat for the same amount of time. Drizzle with the chutney and scatter over the chopped red chilli.
