For decades, culinary snobs have perpetuated a massive myth: that frozen fish is inherently inferior to the fresh catch. We have all experienced the disappointment of cooking a frozen fillet only to be met with a dry, rubbery, and slightly smelly disaster on our plates. But what if the problem is not the freezer, but how you are defrosting it?

Prepare to have your mind blown by a simple, old-school kitchen secret. Whole milk entirely prevents frozen white fish from turning dry and rubbery.

That is right. By simply swapping your standard thawing method for a bath of cold whole milk, you can completely transform your midweek fish supper. The science behind this clever trick is brilliant. As fish freezes and sits in the freezer, it undergoes moisture loss and develops trimethylamine, the compound responsible for that dreaded fishy freezer odour.

When you submerge frozen cod, haddock, or pollock in whole milk to thaw in the fridge, the milk works a double miracle. First, the casein proteins in the milk bind to the trimethylamine, effectively neutralising the harsh smells and drawing them out of the flesh. Second, the rich fat content of the whole milk gently rehydrates the fish, restoring the plump, flaky moisture that is usually lost during the freezing process.

How to use this hack

Take your frozen white fish fillets out of their packaging and place them in a shallow dish. Pour over enough fresh whole milk to completely submerge the fish. Cover the dish and leave it to thaw slowly in the fridge. Once completely defrosted, simply rinse the fillets gently under cold water, pat them completely dry with kitchen roll, and cook as you normally would.

The result? A piece of fish so beautifully tender, sweet, and flaky that even a top-tier fishmonger would struggle to tell it was ever frozen. Say goodbye to rubbery dinners and hello to the ultimate seafood hack!
