Canned Seafood Buying Guide: How to Choose the Right Options

Canned seafood is a pantry staple. Convenient, delicious, and versatile, it can save the day for a meal on the go, elevate an appetizer, or feature in more elaborate recipes. However, faced with the overwhelming selection at online seafood grocers, it's easy to be fooled and have a promise of delight turn into a real letdown.

As the Head of Product Recommendations at Joybuy, my role is to help you cut through the noise. Let's forget the marketing and focus on the facts. We'll review the pitfalls to avoid and the criteria that truly matter, so you never make the wrong choice again.

The 2 Pitfalls to Avoid When Buying Canned Fish?:

1. The "Cover-Up" Sauce?: An overly sweet tomato sauce, a too-vinegary mustard preparation, or a marinade loaded with additives often serves to mask poor-quality fish that is dry or flavourless.
2. The "Olive Oil" Blend That Isn't?: Some labels highlight olive oil, but a closer look at the ingredients list often reveals a blend with less premium oils (sunflower, rapeseed). A true extra virgin olive oil makes all the difference, both in the taste and the texture of the product.

The Essential Criteria for Quality Canned Seafood

A few simple checks are all it takes to avoid these disappointments. Get into the habit of deciphering the label on the back of the can.

1. The Packing Liquid?: More Than Just a Preservative

The liquid the fish is packed in is crucial. It doesn't just preserve the product; it plays a key role in the final taste and texture.

• In Oil?: This is the most gourmet option. An extra virgin olive oil adds fruity notes and tenderizes the fish over time, making it melt-in-your-mouth. Tuna in sunflower oil, which is more neutral, can be an asset for certain recipes.
• In Tomato or Other Sauces?: Ideal for direct use in pasta or over rice. Pay close attention to the ingredients list: favour short lists with little to no added sugar or artificial thickeners. A good mackerel in tomato sauce should taste like fish and fruit, not sugar.
• In Brine (Au Naturel)?: This is the light and healthy choice. The fish is preserved in a simple saltwater solution, which preserves its natural flavour. It's an excellent base for salads or homemade rillettes, where you have full control over the seasoning.

2. The Ingredient List?: Simplicity as a Sign of Trust

A golden rule almost always applies: the shorter the ingredient list, the better the product. For a can of sardines in oil, for example, you should expect to find: sardines, olive oil, salt. And that's it.

Be wary of long-winded lists that include "flavourings," "flavour enhancers," or a series of E numbers. These additions are often unnecessary if the base fish and sauce are of high quality. This also applies to spicy fish or salted anchovies, where the chilli or salt should be the star of the recipe, not get lost among additives.

Frequently Asked Questions About Canned Seafood

How should I store an opened can of fish?

Once the can is opened, do not leave the product in its metal container. The tin can oxidize in contact with air and alter the taste. Instead, transfer the contents to an airtight glass or plastic container and place it in the refrigerator. It's best to consume it within 48 hours.

Does canned fish get better with age?

Yes, but not all of them! Canned sardines in olive oil are known to improve with age. Over the years, the oil tenderizes the fish's flesh, the central bone becomes melt-in-your-mouth tender, and the flavours harmonize. These are known as vintage sardines. However, for fish canned in brine, tomato sauce, or other sauces, it's best to respect the best-before date indicated on the packaging.

What's the difference between albacore and skipjack tuna?

Albacore tuna is considered the most premium variety. Its flesh is light, firm, and has a delicate flavour. It's the preferred choice for preparations where the tuna is the star, like in a Salade Ni?oise. Skipjack tuna has darker flesh, a stronger flavour, and a flakier texture. It's more common and is perfectly suited for rillettes, stuffings, or sandwiches.
