Octopus is a wonderful seafood ingredient, although not as prevalent or as easy to find in the US. Throughout much of coastal Italy you will find variations of seafood salads that use octopus, squid, shrimp, bivalves, and pretty much any type of seafood you can imagine. This particular recipe is made easier by using a jar of ready-made pickled giardiniera vegetables. Be sure to get one that is high in vinegar content and not too spicy. You could also, of course, use your own pickled vegetables.
The octopus is a mollusk belonging to the class of cephalopods and has extremely ancient origins: the most historic fossil dates back to 296 million years and is located at the Field Museum in Chicago. There are more than 300 species of octopus, and despite varying in size and some aesthetic details, they all have the same anatomy. The most common and widespread in Italian waters is the Octopus Vulgaris. It reaches 150 cm in length and the most developed species can weigh over ten kilograms. From an anatomical point of view, the octopus is characterized by the absence of an exoskeleton, which allows it to nest comfortably in the narrowest ravines. It has a globular head with two eyes that, thanks to the position of the retina, have a complete vision without suffering from the so-called blind spot. In the head pouch are found most of the octopus' vital organs, including the three hearts that regulate the octopus' vital flow: two are needed to pump venous blood into the gills, the other regulates the remaining organs. The color of the octopus' blood is blue: in fact, it contains enocyanin, a protein containing copper, that converts to a blue color when in contact with oxygen.
More than 300 species of octopus exist, varying in size and color. The class to which octopuses belong, namely cephalopods, includes five macro categories: octopus, the musky octopus, cuttlefish, European flying squid, European squid. But how to tell the difference between an octopus and a musky octopus? What is the difference between octopus and white spotted octopus or what is the difference between polpo (octopus) and piovra (giant octopus)? Let's see it together
Generally, but not always, musky octopuses are smaller than octopuses. In fact, they turn out to be very similar, as they have 8 arms (not a coincidence that they belong to the order of Octopoda, "eight feet") of equal size, but octopuses have two rows of suckers along each arm, unlike the musky octopus, which has only one. Here is the first curiosity about octopuses, a false myth: octopuses do not have tentacles, but arms equipped with rows of suckers, whereas cuttlefish and squid have 8 arms and 2 tentacles.
The octopus has eight tentacles (which are technically arms, because as explained earlier octopuses do not have tentacles) and in the center of them you find the mouth, which is characterized by a pointed beak - similar to that of parrots - that can be used both as defense and to prey. The octopus uses its tentacles to move by crawling on surfaces, whether it is the seabed or reef, and only occasionally uses the pressure of the siphon, an organ used to expel water that produces a locomotive force. The octopus' tentacles are useful for the mollusk to catch food and carry it to its mouth, as well as to hunt. Half a billion neurons are distributed in the octopus' tentacles, which have their own autonomy of movement: when needed, in the event that a predator forces it to flee, the octopus can detach a tentacle from itself as a distraction and escape.
The octopus is considered the most intelligent animal, it has about five hundred million neurons, two hundred million of which are located in the brain and the other three in the arms. As demonstrated by the Okinawa Institute of Science and Technology Graduate University, the octopus has only one brain. The intelligence of the octopus is very sophisticated and enshrines its behavioral habits. The octopus is believed to be an intelligent animal because it can solve small tasks such as opening a jar containing food, it can use any objects to build a temporary lair for itself (coconuts, giant shells), and sabotage the security systems of aquariums that keep it in captivity, even being able to find its way around in a maze. The octopus is able to camouflage itself with precision: it chooses an element of the seabed and camouflages itself as such, even managing to change the texture of its skin to get as close as possible to the camouflage target, recreating, for example, the ripples of a seaweed. To disorient predators, it uses a jet of ink, which, in addition to facilitating their escape behind the black blanket, physically harms the enemy itself, as it contains an enzyme called tyrosinase that irritates the eyes and reduces the sense of smell.
How are octopus born and how does their reproduction work? The male octopus courts the female and then inserts the hectocotylus, one of eight "tentacles," inside the female's siphon to reach the sac (called the ball cavity) and releases the spermatophores near the ovaries. At the end of the intercourse, the male octopus may detach the hectocotylus to get away: at the end of the intercourse, it is not uncommon for the male octopus to be cannibalized by his mate, so "losing" a tentacle helps the male save himself. After 30 to 40 days of gestation, the female locates a safe shelter and lays the tiny eggs, which she hangs on the rocky walls of a rocky crevice. The eggs average from 50,000 to 400,000, and the mother will not stop watching over them even for a minute, even giving up feeding itself in order to protect its offspring.
Octopus fishing is an activity carried on for centuries in coastal towns by commercial fishermen and also by amateurs, as octopus can be caught by scuba diving, by boat or directly from the shore. There are many techniques to catch octopus:
Should your octopus fishing be successful, you will need to follow a series of important steps to have a perfect final product. The rite of "slammed and curled" octopus is typical in some parts of southern Italy, but if you have bought it fresh and don't know how to clean the octopus at home before cooking it, here are our tips. To clean the octopus, follow these steps:
The octopus nutritional properties are so low in fat and have a high satiating power, making it an ideal food for low-calorie diets. It provides less proteins than other types of fish, but it compensates with the presence of minerals and vitamins, such as calcium, magnesium, phosphorus, potassium, sodium, selenium, vitamin C, vitamin B12 and vitamin A.
Cooking octopus is simple with our tips: you can use it in all your recipes and cook it in multiple ways. Here we will show you how to prepare boiled, steamed, grilled, fried octopus or simply how to cook octopus without water.
Boiling the octopus is the most common and versatile method for cooking it: the octopus is immersed in a deep and large pot, filled with cold water along with a few laurel leaves, pieces of lemon and celery. The water should come to a boil, then be turned off and the octopus left to rest in the pot. The proper procedure involves first soaking only the tentacles in a pot of boiling water, which should be soaked repeatedly to be properly curled.
This is a very gentle way to cook the octopus, as the heat of the steam will prevent the skin from breaking and give back full tenderness. Simply use a steam cooker and cook by steaming the octopus.
Some people boil the octopus before grilling and some people place it directly on the barbecue when raw. Our advice is to boil the octopus beforehand, and then grill it if you do not have a professional barbecue and if you do not have a well-curled fresh octopus.
After a partial boiling, the octopus is then fried - with or without breadcrumbs depending on the tradition and the recipe - in a deep frying pan with plenty of hot oil at a temperature of 180 degrees.
An extremely natural cooking technique, that of the "octopus all'acqua sua (octopus in its own water)". The octopus is cooked in a large pot without the addition of liquid on low heat along with a sauté of cherry tomatoes, onion and parsley and will release "its water" directly into the pot.
Frozen octopus can be cooked directly in the pot, without defrosting. To soften frozen octopus and prevent it from hardening, the care to follow is to soak the octopus in a pot with cold water to avoid a heat shock that could harden the tentacles meat. In this way, the water will gradually come to a boil and you can follow the cooking time according to the size of the octopus and the use you will make of it in cooking.
Octopus cooking time varies depending on the weight of the species itself. Taking boiling as the key cooking technique, it generally takes at least forty minutes on low heat to cook a pound of soft octopus and twenty minutes of resting time with the heat off. To understand if the octopus is cooked there is the fork test: if the tines of the fork easily go through the head of the octopus (which should be soft), then the cooking of the octopus is complete and you can let the octopus rest in a bowl, without water, so that it cools little by little and the meat remains tender and soft.
