1) First up, remove the heads by gently squeezing and twisting them off.
2) To peel prawns, you've got two options - either squeeze the legs at the head end and peel around the body to remove the shell. Or use Nick's preferred method - sit the prawn in one hand and peel down the back of the shell towards the tail with your fingernail. Some choose to the leave the tail section of the shell on for appearance, however this can gently be removed by pinching the end of tail and easily slipping it off to reveal the tail fan.
3) To de-vein the prawn, using a sharp knife, lightly cut along the back of the prawn (not too deep). This cut will reveal the intestinal tract (a black line) - which although not harmful to eat is best removed before cooking. Use the end of your knife to lift it out and discard.
