There’s an old line, usually attributed to Jonathan Swift: “He was a bold man that first ate an oyster.”
Swift called him bold, but I’m not sure bold tells the whole story. Hunger, necessity, and curiosity probably deserve some credit. Most foods don't enter the human diet because someone is looking for novelty. They enter because people are practical: the tide goes out, the net comes up with something unfamiliar, a strange root comes out of the ground, or some unfamiliar critter proves edible once someone learns how to handle it properly.
That is how a lot of good food starts.
Then time passes. The strange thing becomes local food. Local food becomes tradition. Tradition becomes a delicacy. Eventually, someone puts it on a white plate with a few drops from a squeeze bottle and some micro herbs and charges accordingly.
Tinned seafood has its own version of this.
Most people understand tuna, salmon, sardines, mussels, and maybe smoked trout. Then the shelf gets stranger: eel, barnacles, carp, skate, croaker, cuttlefish, sea urchin, garfish, cod cheeks, razor clams, squid in ink, and tins that do not fit neatly into the categories Americans grew up eating.
That doesn't make them stunt food.
But it does command some attention.
Strange Is Often Just Unfamiliar
It wasn't very long ago that raw fish was considered strange by many American diners. Now sushi is sold in airports, grocery stores, office towers, stadiums, and shopping centers. The fish didn't change as much as the culture around it did.
That is worth remembering when looking at an unfamiliar tin. A lot of foods seem strange until enough people start to eat them.
Eel is normal in Japanese cooking. Barnacles are prized in parts of Spain and Portugal. Sea urchin is treated as a luxury in sushi bars and Mediterranean seafood traditions. Cuttlefish and squid have been part of coastal cooking for ages. Skate, croaker, carp, garfish, and other less fashionable fish often reflect the practical intelligence of people who learned to cook what the sea provided.
The oddball tin asks a fair question:
Are you actually opposed to this food, or have you just not learned the context yet?
Eel
Eel makes some people hesitate because it looks more like a snake than a fish.
Understandable. I get it.
But eel can be excellent when it is handled well. It's rich, firm, and often works beautifully with smoke, soy, sweet sauces, or oil. It's not your delicate white fish experience. It has an almost jerky-like consistency to it.
If you already like smoked fish, grilled eel, unagi, or richer seafood, eel in a tin is not as big a leap as it sounds. Try it with rice, cucumber, pickles, scallion, or a squeeze of lemon.
The eels we carry are not baby eels, or angulas. That distinction is important. Angulas are juvenile glass eels, and their harvest is tied to serious conservation concerns, illegal trade, and declining European eel populations. The eels we carry are mature eel pieces with a firmer, richer texture, not juvenile glass eels harvested at the earliest stage of their life cycle.
Cuttlefish and Squid
Cuttlefish and squid belong to the cephalopod side of the shelf, along with octopus.
Texture dominates the conversation. They can be tender, springy, rich, or deeply savory depending on preparation. Squid in ink, stuffed squid, cuttlefish in sauce, and similar tins are often closer to small prepared dishes than plain seafood in oil.
These tins usually want rice, potatoes, bread, or something starchy enough to handle the sauce.
If you already like calamari, octopus, or seafood stews, cuttlefish and squid are not as strange as they look on the label.
Barnacles
Barnacles look prehistoric. That's part of the appeal.
In Spain and Portugal, goose barnacles are not treated like trash seafood or by-catch. They are prized because they are difficult to harvest, tied to dangerous coastal work, and deeply connected to place.
The flavor is briny and direct. They taste like the edge of the ocean. To me, they have the texture of blue crab and the brine of an oyster. I love this tin as part of a larger conservas board. Few tins raise more eyebrows, and few offer more reward to the curious.
This isn't the tin I reach for when someone is afraid of mussels. But for someone who already likes oysters, crabs, or other briny seafood, barnacles are worth exploring.
Serve them simply. Baguette, lemon, razor-sharp white wine. Less is more.
Carp
Carp has a reputation problem in the United States.
In many parts of the world, that reputation would seem strange. Carp is an important food fish across Europe and Asia, especially in freshwater cooking traditions.
A good carp tin can be firm, savory, and much more satisfying than Americans expect. The key is preparation. Freshwater fish can go muddy when handled poorly, so seasoning, sauce, smoke, and producer judgment all weigh in heavily.
If the producer comes from a place where carp is part of the food culture, I am more interested than if the tin feels like a novelty.
Skate
Skate has a long history in French and British cooking, but it never became a major part of the American seafood counter. Fresh skate wing is often paired with brown butter, capers, lemon, or other sharp, rich accompaniments.
In a tin, skate is worth approaching with that same idea in mind. It usually benefits from acidity, fat, or a sauce with some backbone.
This is not a beginner tin, but it is a good example of why the less familiar parts of the shelf are worth exploring.
Croaker and Other Small Fish
Croaker, garfish, and other less familiar small fish often show up in tins because they make sense locally.
Croaker gets its name honestly. Fish in the drum family can make a croaking or drumming sound by vibrating muscles against the swim bladder, which acts almost like a resonating chamber. That sound gives croaker its name.
Croaker are usually bottom-oriented coastal fish. Atlantic croaker, for example, are found around muddy and sandy bottoms, estuaries, bays, and nearshore waters, with adults moving between estuaries and offshore waters seasonally.
That helps explain why they show up in working fisheries rather than luxury seafood conversations. Croaker are familiar to coastal fishermen, recreational anglers, bait markets, and regional commercial fisheries, but they never became a major prestige fish at the American seafood counter.
ABC+ Croaker in Extra Virgin Olive Oil is a good example: a less familiar fish, packed simply in extra virgin olive oil. The fillet is semi-firm, holds together well, and makes a good case for a fish that rarely gets much attention at the American dinner table.
Sea Urchin
Sea urchin isn't subtle. I call it the "black licorice of the shelf." People tend to love it or hate it. Like pineapple on pizza, there aren't many lukewarm feelings here.
Sea urchin isn't where I would send the most cautious beginner. But if someone already likes oysters, uni, anchovies, bottarga, roe, or strong coastal flavors, sea urchin can be one of the most memorable tins on the shelf.
Keep it simple. Toast, rice, butter, pasta, or a spoon. Too much interference, and it disappears.
How to Approach the Oddballs
The mistake is treating every strange tin like a dare. That's not how I think about it.
You don't need to prove anything. You just need to give the tin a fair setup.
Start with one unfamiliar thing, not six. Open it with something plain nearby: bread, rice, potatoes, crackers, or chips. Add something bright: lemon, vinegar, pickles, onion, or peppers. Taste it before you decide it needs adjustments.
I try to understand the underlying culture where these tins come from. What is the history or tradition? How do the locals eat it? What do they drink with it?
These tins are some of my favorite to put on conservas boards. They start conversations, and they often surprise people.
The Reward for Curiosity
Curiosity is a great reason to open a tin. It has certainly been rewarding for me.
Not every oddball will become your favorite. That's fine. You don't have to like everything. The point is to learn the shelf.
Sometimes the tin confirms your suspicion. Sometimes it changes your mind.
The foods that seem strange now may not seem strange forever. Oysters had to start somewhere. Sushi had to cross a line for American diners. Octopus, eel, barnacles, sea urchin, cuttlefish, skate, and carp all have their own stories and their own cooks. These tins are comfort food somewhere.
These tins aren't on the shelf for shock value. They've earned a spot because they represent themselves well.
And they’re only strange the first time.
