Creating delicious butter poached lobster tails can be straightforward with these simple steps:

1. Prepare Lobster Tails: Using kitchen scissors, cut along the top of the lobster shell to expose the meat. Make sure not to cut all the way through; you want to keep the shell intact.
2. Prep the Cooking Liquid: In a medium saucepan, add the butter, water, garlic, and thyme. Bring the mixture to a gentle simmer over low heat.
3. Melt the Butter: Stir the mixture until the butter has completely melted, then increase the heat to medium.
4. Cook the Lobster Tails: Place the prepared lobster tails in the butter. Ensure they are fully submerged. Cook for 12-15 minutes, or until the meat is opaque and cooked through. Adjust the time based on the size of the tails.
5. Season: Near the end of cooking, season the lobster with salt and pepper to taste.
6. Remove and Rest: Carefully remove the lobster tails from the pan, allowing any excess butter to drip off. Let them rest for a minute before serving.
7. Plate and Serve: Serve the lobster tails warm with additional melted butter and lemon wedges on the side.

By following these steps, you'll successfully prepare an incredible dish of butter poached lobster tails that will amaze everyone at your table!
