Butterflying your lobster tail is a technique used before the tail is cooked. To get started, cut down to the middle of the top shell. Then gently lift your lobster meat but make sure to keep the meat attached to the base where the tail meets the shell. Position the meat on top.
This technique allows more surface area of the meat to be exposed during the cooking process. A butterflied lobster tail will cook more evenly, and it will reduce the risk of undercooking or overcooking your lobster meat.
This technique also helps your lobster meat to better absorb spices or marinades used during cooking and help your lobster to cook faster.
