When you purchase lobsters, they most likely be live, and you will put them directly into the steamer pot. But, if you have a leftover lobster tail from a restaurant or you purchased precooked lobster, you will need to reheat just the tails. If you put the tails into a steamer pot, the delicate meat in the tail could fall out since the lobster's shell likely will have been cracked. There is a better way to reheat lobster tails.
Preheat the oven to 176 degrees C (350 degrees F).
Place each lobster tail on a single sheet of aluminium foil.
Sprinkle the water over the lobster tail.
Crimp the aluminium foil tightly around the lobster tail to form a closed pouch.
Place the aluminium pouch on a baking tray and place it into the oven at 176 degrees C (350 degrees F) for 18 minutes. Do not open the foil pouch before the time is finished. Serve hot with butter and lemon if desired.
You can substitute 1 tsp of water with 1 tsp of butter and steam as directed above if you want butter steamed lobster tails. Be sure to use at least 1 tsp of water to prevent the lobster tails from drying out.
