Cooking and cracking a lobster
Advanced Butchery and seafood
Cooking and cracking a lobster is cooking a live lobster quickly and getting the meat out of the tail, claws and knuckles.

How do you do it?
- Keep it in the fridge under damp newspaper, never in fresh water, and cook it the same day. Chill it in the freezer 15 to 20 minutes first.
- Plunge it head first into a big pot of boiling salted water. A 1 1/4-pound lobster takes about 10 minutes once the water returns to a boil; add a couple of minutes per extra 1/4 pound.
- It's done when the shell is bright red and the tail meat is opaque white. Cool briefly.
- Twist off claws and tail. Crack claws with a cracker, hand clear of the blow. Cut along the underside of the tail with kitchen shears.
Why does it work?
Lobster must be alive right up to cooking. After death, its own enzymes quickly turn the meat mushy and bacteria multiply, and you can't tell how long a dead one has been sitting. Fresh water kills it because its body is adapted to salt water. The shell turns red as heat frees a red pigment from the protein that hides it.
What are the common mistakes?
- Storing it in tap water — it dies quickly.
- Cooking a lobster that was already dead — risky; discard it.
- Overcooking — tough, stringy tail meat.
