Due to the coronavirus outbreak Leiths has made the difficult decision to cancel all planned courses (except our online courses) until the end of June. In these exceptional circumstances all students who have booked places on our courses will be offered the opportunity to cancel or reschedule their course. If you are currently in the process of taking a multi-part course, you will be offered new dates to complete the course later in the year. Of course we will be dealing with a high volume of calls and emails and we thank you for your understanding and patience during this unsettling time. We look forward to cooking with you at Leiths in the near future.


When buying a lobster, look for a medium-sized one that feels heavy for its size, indicating good muscle quality, with all legs and pincers intact and not hanging limply. The lobster must be alive, show lots of muscular activity, such as tail flapping, and there must be no frothing at the mouth, which can indicate stress. To store live lobsters before cooking, place in a large container in the bottom of the fridge with a damp tea towel over them. Do not remove the elastic bands from the pincers until after cooking. Only buy cooked lobsters from a trusted source. You can either cook lobsters whole, then remove the meat, or halve and grill them.

...Cook a lobster whole

Before cooking the live lobster, place in the freezer for 20 minutes to sedate it.

  1. Take the lobster from the freezer, place on a board and uncurl the tail and legs. Place a tea towel over the tail and hold on to the tail. To cut through the head, locate the cross on top of the carapace/body shell and place the point of a large, sharp knife in the centre of the cross with the blade towards the head (see step 1, page 221). Push down and then back firmly so the knife penetrates the shell and cuts through the head (see step 2, page 221).
  2. Meanwhile, bring a large saucepan of well salted water to the boil (about 25–30g salt per 1 litre of water).
  3. Place the lobster head first into the boiling water, ensuring it is completely covered in water, then put the lid on the pan and bring the water back to the boil. Lower the heat to a simmer and cook gently for about 8–10 minutes per 500g, until the lobster turns red and the tail tightens against the body. If cooking more than 2 lobsters, cook in batches. Once cooked, remove the lobster from the water and leave to drain well as it cools, before further preparation.

Note You can use a court bouillon (see page 267) to cook the lobster, or more spicy flavours such as ginger, star anise or lemongrass can be added to the water.
