How long do you boil a avarage lobster tail?
Bring the water to a full boil on high heat. Put the lobster tails in for about 5-7 minutes uncovered. If the water starts to boil again, turn the heat down so that it’s just a slight boil. Remove the lobster tails and let them sit in a colander to cool for about 10 minutes before serving. It can help with eating them if you split the underside of the shells first before boiling them with some kitchen shears. Otherwise, it can be kind of difficult to handle them to break the shells open when they’re hot.
