how to cook lobster tails:-The best cooking way is to steam cook them. Steaming them will curl the tails so before steaming, run a wooden skewer through them to prevent that from happening. Use 1 quart or 4-5 cups of water and bring water to a full boil. Place up to 4 average size tails in top steam colander and cover the pot.Lobster will turn red and the flesh becomes white. Allow to steam 1 and 1/2 minutes per ounce . Once cooked, take the steam colander to the sink and run cold water over them which stop the cooking process and allow you to rinse-wash the tails.Serve each person some melted butter in a small cup plus some lemon wedges.
