How to Select, Store and Prepare Cod

When selecting cod fish, just with any other types of fish or seafood it is very important to select fresh fish. Local reputable stores are great places where you can always get fresh fish, including fresh cod.

Cod fillets should be placed on top of the ice, while a whole cod should be buried in ice. If cod is not displayed in these two ways in the store that perhaps it is not safe to consume that kind of cod. When buying cod fish, watch cod fillets. They should have only minimal gaping. Fillets should gleam as well.

You can detect a fresh fish by its smell as well. For this reason, you should get a fresh fish whenever you can instead of getting prepackaged cod. If by the smell it does not smell good to you then you better turn in back to the fishmonger.

Storage is another part where you should pay attention too when it comes to fish. Cod and almost any seafood are very sensitive to temperature. Therefore, you should make sure to put cod fish in the refrigerator as soon as possible. If you leave the cod outside in the room temperature for long, it will get spoiled.

In order to create an optimal temperature for storing cod and other types of seafood, you should use special storage methods. As the temperature in most refrigerators is not ideal for storing fish, you should add some ice to the dish where you have just put your cod. Once you have filled the dish with ice, make sure to put it in the coolest area of the refrigerator, on the bottom shelf of course. Also, if the fish is going to stay for a long time in the refrigerator, for example during the day or even overnight then don’t forget to replenish it with ice.

How long cod can stay in a dish filled with ice in the refrigerator will depend on when the fish was caught. If the fish was caught the same day or a day before you bought it, then it can easily remain stored in this way for about four days without getting spoiled. However, if the fish was caught a couple of days before, then it should remain stored in this way for only a day or two, otherwise, it will get spoiled.
