What each ingredient does

Lobster
Is the main protein; its shell and flesh set the cooking time and final texture.
Coarse sea salt
Seasons the cooking water so the lobster meat is lightly flavoured as it cooks.
Butter
Adds richness and flavour to the cooked meat, especially as a dipping sauce.

The step that matters

Boil briskly for 30 minutes. The water must return to a rapid boil after the lobster is added so the cooking stays even. Overcooking toughens the meat, so the timing matters as much as the heat.
