What are cockles?
Also known as verdigón, the cockle is a bivalve mollusc that lives in salty waters. It belongs to the Cardiidae family and its scientific name is Cerastoderma edule.
The cockle is easily recognised by its shell, which distinguishes it from other species, as it has 22 to 28 ribs that give it a radiate appearance.
Where do cockles come from?
They are found buried in soft bottoms of fine or silty sand, and are located from the coastal strip of the Atlantic Ocean to depths of 10 metres. Likewise, the best Galician cockles are extracted from the estuaries, which contain water that is much richer in nutrients.
Cockles are widely found along the Atlantic coasts, from Norway to the west coast of Africa, passing through Holland, France, Spain and Portugal.
Different sizes of cockles
The different types of canned cockles are classified according to their size. There are 4 different sizes of cockles. In descending order, the different qualities of cockle are: giant, large, third category and fourth category. Of these categories, the most valued is the giant cockle, which has a more intense flavour.
