Lobsters can be boiled or broiled but steaming is more convenient and tastier. Maine Lobsters are superb when cooked the traditional way by simply steaming or boiling.

[edit] Steps

Boil the lobsters by filling a large pot with water.
Add enough salt to get the same salinity as Ocean water.
I prefer steaming them using Salty water
Bring water to a full boil.
Put the lobsters into the pot completely submerged (except if you steam them. I that case, I put approximately 1.5 inches of salt water), and cover. Make sure the cover is air tight and keep the water boiling and time it.
Cook the lobster for approximately 8 minutes, depending on the weight of the lobster. Typically, a lobster that is 1 to 1.25 lbs will take about 5-8 minutes to cook. Lobsters above 1.25 lbs can take up to 10 minutes to cook through.
Allow the lobster to cool completely.
To serve the lobster, start by cutting the tail in half, displaying all the meat.
Break the body with a nut-cracker, use your hands to dig in and enjoy!

[edit] Warnings

If you cook your lobster, make sure it is alive before starting. A lobster dead before it's cooked should not be eaten. Why you ask: Lobter blood contains Copper and if the lobster dies before cooking, the copper oxidize and copper oxide is poison.
