Question: how to defrost and cook frozen lobster tails?
Answer: Thaw lobster tails by placing in refrigerator overnight; or, to thaw same-day, place in a sealed plastic bag and submerge in cold water. Change water every 15 minutes for 1 to 1 1/2 hours, or until fully thawed. Heat broiler to high. Place oven rack in top third of oven.
