Lobster Temperature Guide: Boil, Steam & Grill

Lobster: The King of Crustaceans

Lobster meat is delicate. The tail muscle is powerful and dense, while the claw meat is softer. Cooking them evenly is the challenge.

The Perfect Temperature

• Tail Meat: 140°F60°C. At this temp, it is opaque, firm, and succulent.
• Claw Meat: 135°F57°C.
• Overcooked: Above 145°F63°C, the meat shrinks inside the shell and becomes tough.

Cooking Methods

1. Steaming (Recommended)

Steaming cooks gentler than boiling and prevents the meat from becoming waterlogged.

• Pot: 2 inches of salted water.
• Time:
  • 1 lb: 8 minutes.
  • 1.5 lb: 11-12 minutes.
  • 2 lb: 15 minutes.
• Cue: Shell turns bright red. Antennae pull out easily.

2. Boiling

Best for large batches (clambakes).

• Water: Salt it heavily (like sea water).
• Time: Slightly faster than steaming (subtract 1-2 mins).

3. Grilling (Halved)

Splitting a lobster and grilling it flesh-side up allows you to baste it with butter while it cooks.

• Temp: Medium-High direct heat.
• Time: Flesh side down for 2 mins (sear), flip to shell side for 5-6 mins. Baste continuously.

Frequently Asked Questions (FAQ)

Q: Why is the meat green?

A: This is the tomalley (liver/pancreas) that has melted onto the meat. It is edible, but you can rinse it off if you find it unappealing.

Q: Why is the cooking water blue?

A: Lobster blood (hemolymph) is clear but turns opaque bluish-white when cooked. It contains copper-based hemocyanin, which can tint the water.

Q: How do I kill it humanely?

A: If you are squeamish about boiling/steaming alive, place the lobster in the freezer for 15-20 minutes. This sedates it (dormancy). Then, drive a heavy knife quickly through the head between the eyes before cooking.
