Octopus

What Is Octopus?

Octopus (Octopus vulgaris) is a sea mollusk in the cephalopod class, known for its eight arms. It lives along the rocky coasts of the Aegean and Mediterranean and is known as a highly intelligent, adaptable animal.

Raw octopus has a very firm, rubbery texture, so the right cooking technique—usually a long, slow boil—is essential for tenderizing it.

One hundred grams of raw octopus contains about 82 kcal of energy and around 15 g of protein; it is very low in fat. It is also especially rich in vitamin B12, iron, and selenium.

This is general information; octopus is a food, not a substitute for medical treatment.

How to Choose Octopus

Fresh octopus should have dark brown-purple skin, clear eyes, and feel firm and elastic to the touch.

• It should have a mild ocean smell, not a sharp ammonia odor.
• The suckers should be intact and firmly attached.
• Small to medium octopus generally becomes more tender when cooked.

How to Store Octopus

Cleaned octopus stays fresh for 1–2 days in the refrigerator. Freezing helps tenderize the flesh, so freezing and thawing it once before cooking is a common method.

How to Use Octopus in the Kitchen

Octopus is most often boiled and then grilled, or served cold in salads; proper cooking turns its rubbery texture tender and meaty.

How to Tenderize Octopus

Freeze and thaw the octopus once, then simmer it gently over low heat in a covered pot, in its own juices or with a little water, for 40–60 minutes. It is ready when a fork pierces it easily.

How to Grill Octopus

Marinate the boiled tentacles with olive oil and thyme, then briefly sear each side on a hot grill for 2–3 minutes; the outside becomes slightly crisp while the inside stays tender.

Which Recipes Use Octopus?

Grilled octopus, octopus salad, and boiled octopus are among the best-known preparations.
