Question: how long do you steam a one and a half pound lobster?
Answer: When the water is boiling, quickly add the lobsters to the pot and cover. Steam the lobsters, shaking the pot occasionally, until cooked through, about 8 minutes for 3/4 to 1 pound lobsters, about 10 minutes for 1 to 1 1/4 pound lobsters, and about 11 minutes for 1 1/2 to 2 pound lobsters.
