This recipe can be scaled depending on the size of the prawns you find and the number of people you are cooking for. On the day we cooked this recipe I found these beautiful large tiger prawns that were nearly 1 pound/500 g. Another stand at the fish market had slightly smaller tiger prawns that were probably closer to 2/3 pound / 300 g, which is probably still large enough for one person. Additionally, you can simply multiply this recipe by the number of people you have joining you for the meal.
