I started to develop a recipe for jumbo prawns in 1996 and finally succeeded in a very tasty recipe. These jumbo prawns are not difficult to prepare and will satisfy your desire for an enjoyable meal. I cooked these prawns (shrimp) for a Seafood Dinner for 12 couples in the year 2000, and their comment was that they had never tasted prawns that were so well prepared and tasted so good. Because of their size and cost, one does not want to spoil a tasty prawn. Chilling time for the prawns in the refrigerator is not included in the preparation time.
