2 inches of seawater (or salted water - add 2 tablespoons
of salt for each quart of water) into a pot large enough
to comfortably hold the lobsters. Some cooks also place
a steaming rack large enough to hold the lobsters above
the water, in the bottom. Bring water to a rolling boil
over high heat. Place lobsters in the pot, cover tightly,
return to a boil as quickly as possible and start counting
a lobster for 13 minutes per pound, for the first pound.
Add three minutes per pound for each additional pound thereafter.
For example, a 2 pound lobster should steam for 16 minutes
and a 1 1/2 pound lobster should steam for 14 1/2 minutes.
