Prawn kebabs

Instructions

1. Dry roast the cardamom, cumin and coriander seeds in a small frying pan for 2-3 minutes or until golden and aromatic. Leave to cool.
2. Grind the roasted seeds in a pestle and mortar or coffee grinder until fine. Combine with all remaining ingredients in a bowl. Add the prawns and stir well to coat them all. Leave to marinate for at least 1 hour.
3. Just before cooking, season well with salt. Thread 3-4 prawns onto a skewer and continue until all the prawns are used.
4. Cook under a hot grill for 2-3 minutes on each side until cooked and slightly charred. Serve immediately with wedges of lime.
