Aside from using a wok and the wok recipes here, there are lots of recipes for cooking jumbo shrimp and prawns. Grilling jumbo prawns on the barbeque (barbie) is a great way to prepare jumbo prawns as a meal by themselves or as a supplement to a meal replete with grilled vegetables and maybe a grilled portabella mushroom or two for your vegan friends. Cooking grilled jumbo prawns is a great way to learn how to cook jumbo prawns because you can see right in front of you exactly how the prawns are cooking and learn to recognize when the prawns are cooked just right and ready to be taken off the grill to finish the final cooking with the residual heat left in them so they are perfectly done when you serve them.
