Squid is part of the seafood category and offers a range of nutritional benefits. It is an important source of protein and omega-3 fatty acids. It doesn’t have a strong taste and tends to absorb the flavors of vegetables or herbs it’s cooked with. It has a firm and delicious texture, but it can become tough and rubbery when overcooked. Squids can take on this tough, rubbery texture only when the cooking time is exceeded.
