The preferred method for cooking a live lobster
Cooking times: Start the timer as soon as you put the lid back on
1-1.25 pound lobster = 10-12 minutes
1.25-2 pound lobster – 12-18 minutes
2-3 pound lobster = 18-25 minutes
*Note that cooking times are not cumulative. That is, cooking two 2 pound lobsters should take just about the same amount of time as cooking one 2 pounder. For our two 1.40 pound lobsters, we set the timer for 14 minutes.
Variations
Like they do in Maine, you might also want to steam some mussels and clams alongside the lobster, and serve with boiled potatoes, corn on the cob, and French bread!
