Put the prawns into a large mixing bowl with the squeeze of lemon juice.
In a separate bowl, mix the remaining ingredients. Pour over the prawns and stir well. Leave in the fridge to marinate for a couple of hours. Meanwhile, soak the skewered in cold water for 30 minutes.
Thread 5 prawns onto each skewer and grill under a medium heat for 6-8 minutes, turning once, until cooked.
Serve with salad leaves, wedges of lime and raita for dipping
