1 live northern lobster
Bring 12 cups of water to a boil in a pan that is large enough to accommodate the entire lobster.
Stick a sharp knife in the head of the lobster from the top down, and make a quick 'lever' movement downwards with the knife until it is completely through. This kills the lobster almost instantly.
Add the lobster to the boiling water and cook until it turns a bright red.
Remove and let cool.
Carefully slice the tail open along the midsection and remove the cooked tail meat.
