Live rock lobsters should be humanely killed before you prepare them as below.
Hold the head in one hand and tail in the other, with a tea towel wrapped around the tail to protect your hand.
Twist off and discard the head.
Lay the tail on a chopping board on its back and press gently to flatten. Cut down both sides of the underside of the tail shell using kitchen scissors.
Peel the shell back.
Holding the tail firmly, pull the meat carefully out of the shell; the digestive tract should stay behind, attached to the tail fin.
Trim off the end of the meat, discarding any discoloured flesh. To halve rock lobsters, see Preparing bugs method.
