The high pitched sound made by an overheating lobster is caused by expanding air rushing out of small holes in lobsters' bodies, like a whistle being blown. A dead lobster will “scream” just as loudly as if it was living.
A sound can emit from the shells of the lobsters — a high-pitched sound — but it's due to steam escaping through a fissure in the shell, not the lobsters 'screaming,'” she explained. This doesn't necessarily mean the cooking process is pain-free for the lobster.
Do Lobsters Scream When Boiled Alive? This is a myth, lobsters do not have a voice box or lungs, so they cannot scream. It's more likely that this sound is steam escaping from their shell.
Boiling lobsters alive is a way to reduce the risk of food poisoning from bacteria that live in their flesh and that quickly multiply on their carcasses, according to Science Focus. Plus they have been deemed tastier and better presented on the plate when cooked this way.
Lobsters and other shellfish have harmful bacteria naturally present in their flesh. Once the lobster is dead, these bacteria can rapidly multiply and release toxins that may not be destroyed by cooking. You therefore minimise the chance of food poisoning by cooking the lobster alive.
"If an animal feels pain, you can't just chuck it into a pot of boiling water." Boiling, microwaving, thrashing, drowning and dismembering live crustaceans has been illegal in NSW since 1997.
Scientists have found that it can take lobsters between 35 – 45 seconds to die when plunged into a pot of boiling water — and if they are dismembered their nervous system can still function for up to an hour.
Freeze the lobster for 30 to 60 minutes, then put it in the pot of boiling water head-first. While the boiling water, rather than the freezer, will kill it almost instantly, the cold will immobilize the lobster so it won't thrash about.
American chefs later adopted the process by 1880, when they discovered that the dish looks and tastes better when the animal is boiled alive. It wasn't until later that we realized this also reduces the risk of severe food poisoning. That's all because of these little guys.
Putting cold-blooded animals like crustaceans (or insects) into a freezer or in icy water numbs them, and they don't seem to have pain receptors that react to cold (they do live at the bottom of the ocean, after all).
A lobster does not have a complex circulatory system like we do. Instead of a four-chambered heart it has a single-chambered sac that consists of muscles and several openings called ostia. Their heart lies above the stomach on the upper surface of the animal (but still below the carapace of course!)
Some say the hiss that sounds when crustaceans hit the boiling water is a scream (it's not, they don't have vocal cords). But lobsters and crabs may want to since a new report suggests that they could feel pain.
If one compares the diagram of a lobster's nervous system to that of a grasshopper, the similarities are apparent. Neither insects nor lobsters have brains. For an organism to perceive pain it must have a complex nervous system. Neurophysiologists tell us that lobsters, like insects, do not process pain.
In 1900 the US passed the Lacey Act. It was a law meant to protect plants and wildlife, which it did. But it also eventually made it a federal crime to boil a live lobster.
“As it turns out, lobsters don't mate for life,” explained Mr. Wheir, a video editor in New York. Actually, male lobsters in particular are rather promiscuous. “Lobsters do have a monogamous bond, but it only lasts for two weeks,” said Trevor Corson, the author of “The Secret Life of Lobsters” (HarperCollins, 2004).
When an uncooked lobster is frozen, the meat actually expands and is tightly compressed within the shell walls. When you thaw the uncooked lobster the meat then tears and shreds as the meat shrinks and disconnects from the wall that it was once connected.
Boiling lobsters while they are alive is set to be made illegal in the UK following strong scientific evidence they can experience pain, distress and harm.
Lobster that is steamed is more tender as less water infiltrates the shells. If you have a crowd of people, boiling is the way to go, as it's the best method for cooking four or more lobsters at one time. LobsterAnywhere.com cites the main advantage here is the high, intense heat from the boiling water.
Researcher Michael Kuba says that lobsters are “quite amazingly smart animals.” Like dolphins and many other animals, lobsters use complicated signals to explore their surroundings and establish social relationships.
Put 2 inches of seawater or salted water in the bottom of a large kettle. Set steaming rack inside the pot and bring to a rolling boil over high heat. Add the live lobsters one at a time, cover pot, and start timing. Lobster boiled or steamed in sea water maintains its characteristic ocean taste.
Once you've got your lobsters as dry as possible, wrap them tightly in a commercial freezer bag and freeze at 0-degrees F or lower, and freeze for 9 to12 months. When you're ready to work with them, simply thaw overnight in the refrigerator and boil in salted water for about 12 minutes or until fully cooked.
Once the lobster is cooked (I personally prefer steaming), let it cool down for a few minutes, either with cold water, an ice bath or at room temperature. Remember that the lobster keeps cooking after being steamed, so I prefer to shock it with ice to stop the cooking immediately to prevent over-cooking.
The pigment responds strongly to heat, though: Once you dump a crab or a lobster in a pot of boiling water, it's body chemistry changes: The pigment—astaxanthin—gets separated from the membrane—the crustacyanin—transforming your dinner into that ruby-hued tone we know so well.
Bring the water to a rolling boil. Grasp the live lobster from the back drop it headfirst into the boiling water. Cover the pot and once the water has started to boil again, start timing. Boil the lobster for 10 minutes for the first 1-lb of weight and then 3 more minutes for each extra pound.
