Origin of octopus

These have been around since prehistory. Fossil evidence shows that they have existed since at least the Cambrian period (500 million years ago). The creature had a shell in the early days but lost it over time. Today, these creatures can be found throughout the world in all the oceans. Ancient Greeks ate this dish, drying it out and then grilling it to preserve it. In Ancient Korea, it was a delicacy consumed since the Three Kingdoms period. Live octopi were consumed regularly, a practice that is still alive in Korea and Japan. Some sects of Islam and Judaism forbid the consumption of this seafood.

Commercial production

The world’s main producers are China, Japan, Morocco, Mauritania, South Korea, and Mexico. The main importers are the USA, Italy, Spain, Japan, Portugal, and Canada.

To prepare this food, the head sac of the octopus must first be cleaned to wash out the guts. The beak must also be removed. First, this creature must be tenderized because its meat is extremely tough. One thing to note is that it tends to shrink when cooked, so there must be sufficient meat in the first place. Getting the meat just right is important because it begins to dry out and toughen once it is overcooked.

Octopi are exclusively caught wild from the sea and are not farmed due to problems in hatching and raising. Some scientists and animal rights activists also believe that farming these creatures would be unethical due to their high intelligence. Also, their sustenance would further burden overfished stocks.

Octupi recipes

In some cuisines, this dish is cooked alive and sometimes even eaten raw and alive. It is a popular dish in sushi bars, too. Both lemon and lime juice accompany this food well. Here are a few recipes to try:
