Head to the frozen section of your grocery store. Do not overthink this. Buy the cold-water tails from Maine or Canada; they’re sweeter and meatier. Look for ones that are still in the shell—they cook up juicier.
You want about one 6-ounce tail per person. Or, if you’re having a bad day, get two. I won’t judge. You deserve butter.
Thaw them in the fridge overnight. In a rush? Put them in a sealed bag and dunk them in cold water for 30 minutes. Never use warm water—that’s how you get rubbery sadness.
Now, the magic potion: your boiling liquid.
Fill a big pot with enough water to completely cover the tails. You need room. Crowded tails are unhappy tails. Add a generous fistful of salt—make it taste like the sea. Toss in a lemon, cut in half, and a few bay leaves if you have them.
Want to be extra? Drop in a splash of white wine or a clove of garlic. This isn’t mandatory, but it’s a nice hug for your lobster. You are the chef now.
Bring this water to a rolling boil. I mean full-on, angry, bubbling chaos. Boiling is non-negotiable. If it’s just simmering, your tails will cry.
