You have almost certainly eaten a Moroccan sardine without ever being told you had. The tin might have said France, or Portugal, or nothing much beyond a supermarket's own name, yet the fish inside, and very often the factory that sealed it, belonged to a country that rarely earns a mention on the label or in the conversation. More than half of all the canned sardines in the world come out of Morocco, and it is the one part of the sardine's story that almost nobody thinks about.

The reason is written into the water. Off Morocco's Atlantic coast runs one of the richest upwellings on earth, the Canary Current dragging cold, nutrient-heavy water up from the deep, and where that water reaches the light it grows the plankton that sardines live on. Sardina pilchardus, the same European sardine packed in Galicia and Brittany, runs in numbers no European fleet can match, something over five hundred thousand tonnes landed in a recent year, and it comes ashore really cheap, right beside the ports built to can it.

The industry grew up around that abundance. Safi, a pottery town on the central coast, turned into a sardine port in the 1930s and the sardine capital of the country by the 1950s. It still holds around twenty of Morocco's forty-seven canneries and packs close to a third of the national output, with Agadir and Essaouira and the southern ports filling in the rest. Hundreds of thousands of people now work somewhere along that line, from the boats to the packing belt.

What Morocco built was not a famous name but a capacity, and capacity is quiet. Its factories pack sardines in oil, in tomato, in harissa and in brine, and ship them to supermarkets from Europe to the Gulf to Japan, a great deal of it under other people's names. The cheap tin in the budget aisle, the supermarket own-brand, the sardine that says only packed in the EU, is very often a Moroccan fish off a Moroccan line. It is the unknown engine of the whole category, the volume that keeps a sardine one of the last genuinely cheap proteins on the shelf, run by the country that's least likely to be credited for it.

Engines can be throttled, and in 2026 Morocco throttled theirs. On the first of February it banned the export of frozen sardines, indefinitely, and kept the fish at home. The stated reason was dwindling catches and the need to feed its own people and its own canneries first. The effect abroad was immediate. Galicia's canners draw about ninety percent of their frozen sardine from Morocco, and Spain, which had bought more than twenty-seven thousand tonnes in the first ten months of the year before, suddenly could not. The country that quietly supplies the world had decided, for once, to supply itself, and the shelves of Europe felt it within weeks. The engine had been running the whole time; you only noticed it when it slowed.

An engine is a thing you forget until it stops. Morocco's has not stopped yet, only slowed, but the slowing did what over a century of steady running never could: it made the country visible. The plain sardine in the budget aisle, the one that costs less than a coffee, has always sat at the far end of a long line that begins in a Moroccan upwelling and runs through a cannery in a pottery town on the Atlantic. That was true when the tins were two for a euro, and it is truer now that the cheap can no longer be taken for granted. The cheapest fish in the shop was never cheap by accident.

A tuna-trap village, canning the rest of its catch.

Campisi has worked out of Marzamemi since 1854, the little Sicilian port whose tonnara, the Arab-built tuna trap, was once the most important on the island's eastern coast. The house is known for its bluefin, but this is the other Sicily in a tin: cernia, grouper, a firm white fish of the rocky Mediterranean bottom that rarely reaches a can at all.

The fish is packed in olive oil with capers, the salted flower buds that grow wild across the Sicilian southeast and season half its cooking. Grouper holds its shape where a softer fish would shred, so it comes out of the tin in clean white pieces, mild and faintly sweet, the capers cutting the richness with a briny snap.

It eats like a small Sicilian lunch already assembled. Flake it over pasta with some of the oil and a squeeze of lemon, pile it on toasted bread with a slice of tomato, or eat it straight with a fork and let the capers do the seasoning.
