Katsu ika odori-don

from Wikipedia, the free encyclopedia

Katsu ika odori-don ( Japanese 活 い か 踊 り 丼 'Squid actively dancing in the bowl ' ) is a Japanese dish consisting of a fresh squid on either rice or noodles. When soy sauce is poured over the meat, the muscles begin to move. The dish is usually served with salmon eggs and other side dishes in a bowl.

preparation

Cooked noodles or rice are put in a bowl and garnished with other ingredients such as salmon eggs . The cook then takes a live octopus, removes its beak and cuts off its head. Then some offal and the meat are cut up and placed on the side dishes. The squid arm “crown” is placed on top. At the time of serving, the divided squid is immobile - until the moment when soy sauce or another sodium-containing (i.e. salty) liquid is added. Occasionally the movement of the squid is so intense that the body escapes from the shell.

origin

The dish is a modification of the traditional Japanese dish " ika-don " by a sushi restaurant called Ikkatei Tabiji , which is based on the island of Hokkaido in the Japanese prefecture of the same name . With the renaming to " odori-don ", the squid was no longer served in slices as before, but as an almost complete animal.

Cause of the movements

The squid appears to be alive, but is dead due to the severing of the head with the brain and heart necessary for life. The movements arise from a purely physiological-physical phenomenon. The soy sauce usually served with this dish is rich in table salt and thus in sodium and chloride ions. The sodium ions trigger muscle contractions by opening the channel pores of the muscle cells and the resulting influx of calcium ions, just as the action potentials of the nerves do in living animals (and in the same way that movements of salt or electricity can be induced in fresh frogs' legs), at least that way long as there is still a sufficient supply of the energy supplier adenosine triphosphate in the cytosol of the cells. These muscle movements in the cephalopod arms act like a "dance".
