Broodje Haring

At a haringkar, the herring cart parked on a Dutch quay or street corner, the fishmonger lays a butterflied herring on a board, showers it with diced raw onion, and either hands it to you whole by the tail or chops it into bite-sized pieces stuck with a tiny paper flag. The broodje haring is that same fish put inside a soft split roll instead of eaten off the hand, raw and cool and oniony, the cart ritual made into a walking lunch. The fish is the point, and almost nothing else is on the roll.

What is in the roll is barely cooked at all. Hollandse Nieuwe is a young herring caught before it spawns, when its fat runs high, then cured only lightly in salt rather than smoked or pickled to firmness. The pancreas is deliberately left in the fish during curing because its enzymes ripen the flesh to something soft, glossy, and faintly sweet rather than fishy. The result is closer to a cured raw fish than to anything tinned, and it sits in the bread silky and pale, with a clean saline finish and none of the sharp brine of a rollmop.

The build is unforgiving precisely because there is almost nothing to it. A stale or crusty roll fights the tender fish and wins; the bread has to be soft enough to compress around it without shredding the fillets. Too much onion buries the herring's delicate sweetness under raw allium; too little and the fish reads as flat. Warmth is the real enemy. Herring this lightly cured needs to stay cold to stay clean-tasting, and a fillet left out turns oily and strong within the hour, which is why a good cart keeps the fish on ice and dresses each one to order.

You smell brine and sharp raw onion before anything else, and the first bite is cool and yielding, the fish almost dissolving against the soft crumb. There is the slip of the fillet, the crunch and sting of onion, the faint sweetness underneath the salt. Some carts add slices of sweet-sour pickle for a vinegar snap against the richness. It is a strange, oceanic, savoury thing to a first-timer and a deeply familiar one to a Dutch eater, and it goes down in a few bites standing at the cart.

The cultural argument is about method, and it splits the country. The Amsterdam way is to have the herring cut crosswise into chunks, piled with onion, and eaten with a cocktail pick, often topped with a little Dutch flag. The older Rotterdam and southern way is to take the dressed fish by the tail, tip the head back, and lower it whole into the mouth. Putting it in a roll sidesteps the whole dispute, and that is partly the broodje's appeal: it is the herring for people who want the fish without performing either version of the ritual in public.

The new catch is a calendar event. The first barrels of Hollandse Nieuwe each year are landed in early summer and sold with real ceremony, the season marked by the flag-decked boats of Vlaggetjesdag in Scheveningen. The early fish commands a premium and a small frenzy. Outside that window the carts sell maatjes from the same cure, kept frozen and thawed, so the broodje haring is available year-round even though its prestige peaks for a few weeks in June.

Its relatives on the same cart are easy to name and easy to keep separate. The kibbeling, battered and deep-fried white fish with garlic sauce, is the hot, cooked, anonymous-whitefish cousin, the opposite of the raw single-species herring in every respect that matters. The broodje makreel uses hot-smoked mackerel, cooked and firm where the herring is raw and soft. The rollmop, a herring rolled around onion and pickled in vinegar, shares the fish but cures it to a sharp, firm, sour thing that the lightly salted Hollandse Nieuwe is defined against.

The Fish That the Pancreas Makes

The thing that makes Hollandse Nieuwe possible is a medieval gutting trick. Dutch fishermen developed gibbing, kaken in Dutch, a way of cleaning herring at sea that removes the gills and most of the guts but leaves the pancreas in place so its enzymes can ripen the salted fish. Tradition credits a fourteenth-century Zeeland fisherman named Willem Beukelszoon with the method, though that attribution is more national folklore than documented fact and should be read as legend rather than record.

What is firmer is what the technique unlocked. A preservation method that let lightly salted herring keep and ripen turned the North Sea catch into an export staple and a piece of national identity centuries before it became a street snack. The herring fishery underwrote a real share of the Dutch economy in its great age, and the annual landing of the season's first fish has been marked for centuries: a Vlaardingen festival celebrating the boats setting out for the catch is attested in a newspaper as early as 1787, and the modern flag-waving Vlaggetjesdag took its present shape in Scheveningen in 1947. The roll has no inventor and no origin date worth inventing; it is simply the cart herring moved into bread, and its honest anchor is a young North Sea fish gutted by a method old enough to be wrapped in legend, cured soft with its own enzymes, and eaten with raw onion on the quay.
