Clean the prawns if that hasn’t been done yet. Remove the heads and peel them. Slice their backs open and remove the black vein. Put them in a mixing bowl. Peel one garlic clove. Mash it under the blade of your knife. Add the mashed garlic, brown sugar, paprika powder and cumin seeds to the bowl as well.

Stir the prawns and then pour in the orange juice and lemon juice. Season it all with a pinch of salt. Stir again.

Then add the hot chili sauce to the bowl.

Stir the prawns and the spicy marinade well. Cover the bowl with some cling film and put it in the fridge to marinate for an hour until chilled well. Stir them regularly. Then in the meantime soak 8 wooden skewers in some water to prevent them from burning later on. Remove the marinated prawns from the spicy marinade. Divide them over the skewers. Place them on a baking tray. Drizzle with the remaining marinade.

Grill the prawns under a hot grill for a few minutes. Turn them over and grill the uncooked side for another few minutes. The prawns should be cooked through. Put the skewers on a serving dish or plate. Serve the prawn skewers hot.
