Butterflying prawns is the process of cutting them in half lengthways and flattening them out. It’s useful for grilling and barbecuing.
-Uncurl the prawn, belly-side facing upwards.
-Cut a line from underneath the head of the prawn to the tip of the tail using a sharp knife, making sure the knife cuts through the meat but not the outer shell of the prawn.
-Open up the prawn fully. If you like, you can remove the black intestinal tract from the prawn by scraping it out with the tip of a sharp knife. This is called ‘deveining’.
-Grill on the butterflied side.
