Fish deteriorates very quickly after purchase. It can be frozen to preserve it, but respecting certain rules.
Source of protein, minerals, vitamins while being lean or source of “good cholesterol”, fish is a product that has many health benefits. It is also often renowned for its finesse. On the other hand, its preservation is delicate, as evidenced by the ice cream stalls in fishmongers.
Seafood deteriorates very quickly. Fresh fish should be refrigeratedr within two hours or bacteria may grow. Its smell and taste will then change. And even well kept in a cool place, its qualities will deteriorate after two or three days, even if it will remain edible. Fish lovers can therefore bet on freezing. This is still the best way to avoid having to go to the fishmonger’s each time he wants to cook some, while betting on an artisanal product. So you have to follow certain rules.

Indeed, the fish can be kept for several months in the freezer.provided it is well conditioned. Due to its rapid deterioration, it is better to freeze it immediately after purchase rather than after a few days. We will also avoid washing it to limit the presence of water, unless the skin is still present on your piece. In any case, it will have to be gutted to prevent the entrails from bringing a bitter taste. A piece of fish should be frozen flat, ideally in a bag. Given its water content, it could otherwise form a large block if not stored correctly. Thus, a fatty fish can be stored without problem for three months and a white fish up to six months. For safety, it is still better not to wait until the last moment to consume it.
Care should also be taken when defrosting. Ideally, we will leave the fish thaw gradually by leaving it overnight in the refrigerator. You can finish the process by placing it on a wire rack over a dish, to make sure it doesn’t soak in its thawing juices. However, if you are in a hurry, you can thaw it more quickly by placing it in an airtight bag and immersing it in a pan of lukewarm water.
