How to clean the calamari
Wash the squid under running water.
With one hand grasp the head of the calamari and with the other, the body gently pulls the head to determine the detachment of the entrails.
Eliminate the transparent rigid internal structure that supports the calamari's body (the gladius) being careful not to break the bag.
Remove the skin.
From the head of the calamari remove the beak that is in the center of the tentacles with the help of the scissors.
Take out the eyes and rinse under cold water and once cleaned the calamari we can then cut the bag into round pieces and leave the tentacles intact.
How to cook them
In a pan, fry the chopped onion in oil, add the peeled tomato as soon as it is golden, add salt and pepper, simmer for at least 15-20 minutes over medium heat.
Add the cleaned and cut calamari, mix everything together, and add in a glass of white wine.
Cook for at least 20 minutes, until the liquid evaporated. Add more salt and pepper if you need it.
Turn off the heat, put it in a serving dish, and sprinkle with chopped parsley (optional).
