Seafood, also known as shellfish, refers to any food produced from marine animals with a shell. Common types of seafood include crabs, clams, oysters, scallops and lobsters.
Crustaceans are aquatic arthropods with long, soft bodies and joined shells, legs that allow them to swim and move. Common examples include lobsters, crabs, prawns and shrimp as well as the crayfish which has no spines and is covered by a hard shell.
Clams, commonly referred to as clams, are an invertebrate group of bivalve mollusks with hinged shells that open and close in order to propel themselves through water. There are over one hundred varieties of clams worldwide.
Clams can usually be eaten raw, though some must be steamed or cooked for a short period. For an easy yet flavorful dinner, try making some clam chowder or linguine alla vongole with fresh clams and white wine.
Many frozen clams can be purchased frozen. Be aware that frozen clams may spoil if left frozen for too long or when thawed and refrozen before cooking. Be wary of frozen clams with signs of frost or ice crystals on their shells.
When selecting seafood for any dish, the selection process is essential. Always perform a “tap test” on live clams, oysters and mussels before selecting them to guarantee they will close when tapped and have leg movement. This helps guarantee the highest possible quality product.
Selecting the Appropriate Ingredients
Fish, clams and oysters can be season with a variety of spices, herbs and other ingredients. Salt, pepper and other seasonings are especially popular for enhancing seafood flavours. Incorporating citrus fruits, herbs and garlic into seafood dishes is another popular way to add an extra layer of zest and taste.
Some seafood, particularly fish, clams and oysters, can be easily contaminated by harmful pathogens like bacteria and parasites. Therefore it’s essential to thoroughly clean the surface of these items before cooking or prepping them. The best way to do this is by hand with a brush or spatula.
Depending on the type of fish, it may be dried, salted or pickled to preserve and extend its shelf life. Dryed, smoked or salted fish can then be made into dishes such as terrines and sashimi for added nutritional value.
In addition to being a source of vitamins and minerals, many seafoods are high in protein – particularly certain varieties such as salmon.
When selecting seafood, it’s essential to take into account the species and size. Smaller fish tend to be more flavorful than large ones and cook faster as well.
Other factors to consider when grilling fish include the temperature of the water where it was caught and its species’ diet. Fish that are high in fat or proteins will taste better when grilled than leaner varieties.
Certain species are more vulnerable to disease and infection than others, so it’s wise to choose a variety that has been sourced from an established supplier. Furthermore, fish that is harvested from the same waters as other sensitive species should not be consumed. Furthermore, buying sustainable sources is recommended; this helps conserve the environment and reduce fishing pressure on our precious marine resources.
