So how do you cook them? First "anaesthetise" them in a bucket of ice for about 20 minutes. They can then be butterflied (cut in half), brushed with olive oil and some diced garlic, and thrown onto a barbecue. To cook them quickly, Kris Gaunt of Mulataga recommends covering them with a large pan lid for a few minutes so that they steam in their own cooking juices.
