Methods For Freezing Fish

Freezing fish is not just about tossing it into the freezer. There are several methods to ensure that your fish stays fresh and delicious, minimizing freezer burn and preserving taste.

Before freezing, it’s important to start with fresh fish. Not sure how to spot a high-quality catch? You can learn how to tell if a fish is bad in our comprehensive guide.

No matter which method you choose to use to freeze your fish you should always start with these three steps:

1. Select the freshest fish possible. Look for clear eyes, a mild scent, and firm flesh that springs back when pressed.
2. Rinse the fish under cold water to remove any dirt or scales.
3. Remove its scales, or fillet it before freezing, now is the time to do so. Clean the fish’s cavity and remove any organs or entrails. If filleting, carefully separate the fish into fillets following proper techniques.

Ice Glazing

Ice glazing involves dipping the fish in cold water and then freezing it. After the water has frozen, you repeat the process several times to create a protective layer of ice around the fish.

Although if not done properly this method can cause your fish to become mushy when you thaw it.

1. Freeze the Fish: Lay the fish on a tray lined with parchment paper. Put the tray in the freezer until the fish is frozen.
2. Glaze the Fish: Once frozen, dip the fish quickly in cold water and return it to the freezer. This will create a thin layer of ice around the fish.
3. Repeat: Continue dipping and freezing until you have a good layer of ice around the fish. This can take 2-3 rounds depending on the size of the fish.
4. Package: Once the fish is thoroughly glazed, place it in a freezer bag, squeeze out the air, and seal it tightly.

Vacuum Sealing

This method requires a vacuum sealer, a machine that removes all the air from a plastic bag before sealing it. Vacuum sealing can be a little more expensive due to the cost of the machine, but it is extremely effective at preserving fish.

1. Place Fish in Bag: Put your fish in a bag compatible with your vacuum sealer.
2. Seal the Bag: Use your vacuum sealer to remove all the air and seal the bag. Make sure the seal is tight and secure.

Wrapping in Plastic

If you don’t have a vacuum sealer, you can also tightly wrap your fish in plastic wrap, then place it in a freezer bag. While this isn’t quite as effective as vacuum sealing, it’s a good budget option.

1. Wrap the Fish: Wrap your fish tightly in a layer of plastic wrap.
2. Package: Place the wrapped fish in a freezer bag, squeeze out the air, and seal it tightly.

Guide to Freezing Different Types of Fish

How you freeze your fish can also depend on what type of fish you have. Here’s a quick guide to freezing common types of fish.

Type of Fish	Freezing Method	Notes
Salmon	Vacuum Sealing	High in fat, vacuum sealing prevents freezer burn best
White Fish (Cod, Haddock)	Ice Glazing	Low in fat, these types are less prone to freezer burn
Shellfish (Shrimp, Lobster)	Vacuum Sealing	Delicate and prone to freezer burn, best preserved with vacuum sealing
Tuna	Ice Glazing or Vacuum Sealing	High in fat but often sold as steaks, either method works well

For guidelines on safe freezing practices and food preservation, refer to the FDA’s recommendations on freezing and food safety.

How to Thaw Frozen Fish

To enjoy your frozen fish, you’ll need to thaw it. Here are two common methods:

1. Refrigerator Thawing: This is the safest and most recommended method. Simply move your frozen fish from the freezer to the refrigerator and let it thaw slowly over 24 hours.
2. Cold Water Thawing: If you’re in a hurry, place your sealed fish in a bowl of cold water. Change the water every 30 minutes until the fish is thawed.

Never thaw fish at room temperature or in warm water, as this can allow harmful bacteria to multiply.

Top Tips for Freezing Fish

Here are some quick tips to remember when freezing fish:

• Always clean and prepare the fish before freezing (remove guts, scales, etc.).
• If freezing whole fish, consider freezing them individually to avoid them sticking together.
• Label your packages with the type of fish and the date it was frozen.
• Eat your frozen fish within 3-6 months for the best quality.

Now if you are not ready to freeze your fish immediately. Proper storage is crucial to maintain freshness until you’re ready to move to the freezing step.

To help with that, we’ve outlined the best practices for storing fish in our detailed guide. Remember, the goal is to keep the fish as fresh as possible until it’s time to freeze.

Conclusion

Knowing how to freeze fish properly will help you get the most out of your seafood, whether you’re saving a supermarket bargain, preserving a successful fishing trip, or simply ensuring you have your favorite protein on hand for future meals.
