There are two types of people in this world. Those who fastidiously use a knife and fork to peel away the shell, and those (like me) who like to get their hands in. This is for those of you who are like me! Break off the head and discard it. Some people like to suck the juices from the head - I don't, but I've been reliably informed that the head is the best part! Peel the shell from the prawns, starting at the slit that was cut down the back, and pulling the shell and legs away. Dip the prawn into a dipping sauce, pop it in your mouth, close your eyes and enjoy. You may also feel the urge to say 'mmmmmmm' while you are eating it. This is perfectly normal behaviour and nothing to be concerned about. Wipe your hands on a serviette and repeat!
