Frozen fish

Marinating fish is simply immersing portions of fish in marinades of preference over some time to add a particular flavor or taste. Marinades help to reduce the rigid texture of fishes, but you might be wondering if fish can remain in a marinade over a long period. Improvements in the taste and quality of fish are going to be noticed.

However, it is essential to know whether you can marinate a frozen fish before consumption. Marinating is a very productive way to introduce more moisture into fish to enhance its taste before cooking. Marinades for fish could be made at home or purchased at stores.

Can you marinate frozen fish? Yes, you can marinate frozen fish. The outcome won’t be as great as marinating thawed fish; you’ll still obtain a tender texture and delicious flavor, but thawing produces the best form. The best marinades for frozen fish should contain some acidic liquids and seasoned oil of your choice; these will guarantee a satisfactory level of juiciness, tenderness, and a lovely flavor.

When attempting to marinate fish, the type of fish has to be considered. There are two types, firm and flaky. A firm fish can take a more potent marinade for a longer time compared to flaky fishes. Fishes like black seabass, swordfish, and pearl-fish are healthy fishes and can take a more potent marinade than codfish, a crispy fish. Examples of flaky fish (think small fish) are salmon, trout, and cod. Once you marinate a flaky fish for an extended period, it can fall apart when you are trying to cook it.

Things to Know When Marinating Frozen Fish

Always use an oil-based marinade: To protect the outer texture of the fish, to make it crisp and brown, you have to use an oil-based marinade so you won’t get the fish all messed and scattered while cooking. That is why cooks advise consumers to avoid a water-based marinade and suggest that they always pat fish fillets with paper towels before cooking to absorb any water on the fish’s skin. 

One thing to expect when marinating frozen fish is that excess water will cause steam during the cooking process which will not create a crisp, brown skin for the fish. When purchasing a marinade or when creating a homemade marinade, you must ensure it is oil-based.

Please don’t leave your fish in a marinade too long. It is essential to know all marinades contain acids like citrus juice or vinegar juices. If you let your frozen fish sit in an acid mix for too long, it will overpower the fish, which is not what you want. When you prepare a frozen fish marinade, be sure only to use a small amount of an acidic ingredient and don’t leave it in the marinade to protect the fish’s texture before cooking.

How to Marinate Frozen Fish

Marinating frozen fish is not advisable because of how delicate the texture of a fish. Do not defrost fish at room temperature or in hot water because bacteria can multiply, and the surface can be affected when immersed in hot water. Put in a sealed bag for safety, preserve the flavor, and get it submerged in cold water until it is defrosted.

These specific processes need to be followed:

Since you’ve decided to marinate your frozen fish and to marinate directly is going to be difficult, you have to devise other ways by which you can get the fish ready for marinating,

  • Start by preparing your preferred marinade. Get the essential ingredients for the marinade, or you can buy them ready-made from stores around you; marinades could contain some acidic juice, like lime juice and seasoned oil. 
  • Dip the frozen fish in a microwave to get the fish to a suitable temperature for marinating.
  • Store in the refrigerator after marinating to prevent the introduction of bacteria into your well-marinated fish.
  • Once the frozen fish has absorbed a significant amount of the spicy marinade, take it out of the fridge in preparation for cooking. 

Alternative Methods – Allowing Frozen Fish Thaw before Marinating 

You can also thaw your frozen fish by immersing the frozen fish in some cold water. Replace the cold water from time to time as it cools off, change it with some fresh cold water, and repeat the process for about 30 minutes. Once the fish is thawed, you can then marinate it and cook.    

Try putting frozen fish in the refrigerator overnight to get the temperature to the easy-to-marinate point. A night before you know you want to cook fish, put it in the fridge so it will slowly defrost. This process keeps the fish at an always cool temperature while also allowing it to thaw completely.

Also, this makes it easy for frozen fish to thaw completely, although it might take time. Once you do that overnight, it would preserve the taste and texture.
