What's Inside?

Why We Love It

The butter this tuna is preserved in is handmade by a lone neighborhood dairy farmer, Carmela. She milks her cows every day at 7am, churning butter using classic, traditional methods without modern-day machinery. One bite of this butter has the ability to transport Galician locals back to days of their youth!

How To Eat It

Heat it before ya eat it. Temper the tin before eating by steeping it in warm water for a few minutes. When the tin is warmed through and the butter is silky, simply eat the contents straight out of the tin, pour over fresh pasta, slather on quality bread, or endeavor to make TUNA BUTTERED POPCORN. Call me when you get there!

About Island Creek x Mariscadora

Like the start of any good story, Mariscadora begins with an accountant and a fisherman. Founders Angel Costas and Floriano Miñan first met at a now defunct cannery where Costas ran the books as an accountant, and Miñan applied his lifelong knowledge of local seafood as the cannery’s purchaser. In 1966, sensing that bankruptcy was on the horizon for their employer, Costas and Miñan decided to jump ship and start their own factory. Mariscadora is the inhouse line of tinned seafood for the cannery.

The ocean has shaped the culture, cuisine, and economy of Galicia for centuries. Nicknamed “the land of a thousand rivers”, Galicia is studded with bays and inlets which are fed “rías” (aka estuaries). It's this magical brew of the fresh and salt water that makes Galicia one of the most prolific shellfishing and fishing regions in the world.

How do I eat/serve tinned fish?

Ideally, you can just eat it straight out of the tin—so long as you're buying high quality products (but that's why you're here, isn't it?). For a simple preparation, you can put it toasted sourdough bread or crackers, with a little mustard and pickled vegetables for some balanced acidity.

How long will it last once I buy it?

Tinned fish lasts a very long time. We generally say it's best to consume the product by the "Best used by" date printed on the tin for best results, however people have been aging tins for generations. These products are completely shelf-stable and should last at least 3-5 years un-opened!

Why is tinned seafood more "sustainable"?

While not unequivocal, there are definitely environmental benefits to tinned seafood. A few reasons include: Increased traceability, shelf-stable, zero food waste, recyclable materials, and lower-footprint supply chains.

Why is an oyster farm selling tinned fish?

Tinning fish is a time-honored way of preserving seafood at peak freshness that has sustained families for generations; not only on the dinner table, but by providing a stable income to small coastal communities around Europe. At one time, tinned fish was even served to inmates in local prisons and was the main protein source for lower income families along remote coastlines. This history is reminiscent of the popularity of oysters here in the United States during the 19th century, when the abundance of wild oysters gave economic stability and affordable protein to working class families for decades until oyster stocks were depleted.

As an oyster farm, we’re diehard evangelists of the benefits of responsible ocean farming. We see aquaculture as an integral part of our future global food system. With the ability to grow shellfish, we reduce the dependency on wild stocks, decrease the excess of nitrogen in our oceans, and create meaningful jobs in coastal communities. Everybody wins.
