Tips for Buying the Fresh Fish

When you’re selecting the best quality raw fish from the grocery store or fish market there are things you can look that’ll ensure you get top quality fish every time:

  • Smell: The way fish smells is one of the most important indications to its freshness. It may seem natural that fish should have a “fish smell.” But that is actually a sign that your fish, whether you’re buying a whole fish or fish fillets, are passing their prime. Good quality raw fish should have a neutral or almost cucumber-like smell.
  • Check the eyes: If you’re buying a whole fish, look at the eyes. Fresh fish will have moist, plump and clear eyes. If the eyes have clouded and appear dried out, that is a sure sign the fish is not at its freshest and should be avoided.
  • Skin: When you’re looking at the fish, the skin should be shiny, and the scales should be closely fitted together. If the skin is dry or has a dull color and the scales are flakey, that is a sign of age.
  • Texture: You may not always have the option to feel the fish before buy it. But if you can, then look for fish that feels firms to the touch. It should easily bounce back when you press on it. A mushy and slimy texture is a sign that fish has started to age.

How to Store Fresh Fish

If you are purchasing multiple things at the grocery store, wait to pick up the fish right before checking out. You’ll want to take your fish straight home and get it in the fridge as soon as you can. Store seafood or fish fillets wrapped in butcher paper or a plastic bag, then place it in a shallow covered container to prevent it from leaking on to the shelves in the fridge.

Once you’ve wrapped it, slip it down into a freezer bag or wrap it in a layer of freezer paper. For best results, you’ll want to eat it within 6 months of freezing.

What’s the Best Way to Thaw Frozen Fish

For thawing frozen fish, just place it in the fridge overnight. You can also do a quick thaw by placing the frozen fish submerged in cool to cold water. If it’s not thawed within 30 minutes, change out the water with fresh cool water. Fish thaws quickly this way so don’t leave it out too long.

Fish should never be thawed at room temperature because warmer temps could cause bacterial growth.

It’s important to understand the shelf life of fish before purchasing it. As a good rule of thumb, you should cook it the day you buy it. But if you have refrigerated fish, the absolute maximum you can keep it before cooking or freezing is 1-2 days. While it can be expensive to have to throw it away after a couple of days, it’s a much better alternative to risking food poisoning.
