How to thaw frozen whole lobster
In the fridge
Safest. Allow about 24 hours per 5 lb (2.3 kg); small packs thaw overnight. Once thawed, raw meat and seafood keep 1–2 extra days in the fridge.
In cold water
Seal it in a leak-proof bag and submerge; change the water every 30 minutes. Allow about 30 minutes per pound, then cook right away.
In the microwave
Use the defrost setting and cook immediately — parts of the food may start to cook.
