In the tinned fish world at Zingerman’s, Ortiz tuna is the belle of the ball. Each year we sell a boatload of it. It’s delicious, and it certainly merits all the attention it gets, but it’s not the only tinned fish in town. Portuguese sardines are equally delicious, though comparatively unsung.
Sardines were the original convenience food.
In the early 1800s, Pierre-Joseph Colin was the first person to can fish, and the first fish he canned was the sardine he grew up eating in Brittany, France. By 1836, his factory was producing about 30,000 tins per year. Every tin was made and packed by hand. Most of them were used to feed the French military. The soldiers used their bayonets or rocks to smash open the tins, since the can opener wouldn’t be invented for another twenty years.
For more than a century, tinned sardines dominated the market for quick, prepared convenience food. They filled workers’ lunch boxes and government pantries stocked up for bomb threats. In the middle of the 20th century, tinned sardines were the student’s equivalent of today’s ramen—cheap and quick food (and, unlike ramen, fairly nutritious). With the rise of TV dinners and other pre-made meals, sardines fell off their prominent perch. Their workaday reputation, though, has remained.
On the other side of the Atlantic, sardines are fancier fare.
In 1935, Oscar Wilde’s son started London’s first sardine tasting club. And Jose Carlos Capel, the food critic of Spain’s most widely circulated daily newspaper, once said, “In the larders of some European gourmets, tins of sardines in olive oil occupy a place of honour alongside pots of foie gras with truffles or jars of caviar. A cult has built up around these canned fish, which… constitute a kind of gastronomical religion.”
Perhaps no country loves its sardines more than Portugal. The Golden Book of Portuguese Tinned Fish from 1938 reported that “among the great variety of Portuguese tinned fish, the sardine occupies the most important place.” Lisbon is still a working fish port. Sardines account for a third of the fish brought in each year—a fact that’s even more remarkable when you consider that sardine season in Portugal is only six months long, from May to October.
You can get good tinned sardines from around the Mediterranean.
There are producers in Spain, France, and Portugal that all offer high quality fish. From these countries, the sardines are generally pilchards. What we call “sardines” can actually be any of a handful of different small fishes, including ones from the herring and sprat families. Pilchards are the fattest and most tender. Labeling laws require that any non-pilchard fish canned as “sardines” must include an identifying label on the inside of the tin.
Good Spanish and French sardines have a subtleness to them; Portuguese sardines tend to have a bit more of an edge. It could be described as being more briny, or just more intense. One Portuguese sardine afficionado I know described it as a “tsk tsk tsk”—a certain extra succulence she couldn’t quite put to words.
We get our Portuguese tinned sardines from the La Gondola cannery, packed under the label da Morgada. Many of the fishermen are the second generation to work for the company. They tin the sardines only during the sardine season with fresh, not frozen, fish. Each tin is still packed by hand, just like they did in France in 1836, with four or five fat fish nestled in olive oil (as pictured). We sell tins packed with pure olive oil and ones packed in extra virgin olive oil. Both are fantastic; the ones in extra virgin oil are a bit softer, rounder, more buttery. The sardines in pure olive oil are packaged in a handsome box designed by Zingerman’s artist Ryan Stiner.
Sardines packed in olive oil get better with age.
Just like aging cheeses or wines can produce more intense flavors, tinned sardines packed in olive oil that are aged for a few years—or even a few decades—can develop bigger flavors. Having a collection of vintage sardines may not be as flashy as having a cellar full of aging wines or a humidor filled with good cigars, but it can make for some very good eating. Starting a sardine collection is easy: just pick up a few tins, keep them somewhere cool and dry, and turn them every now and again so they age evenly. Make sure you’re using very good sardines since aging them will emphasize the flavors that are already there. Good sardines will get better while inferior sardines will taste increasingly mediocre.
