Carlitos

In 1953, at a bar called Cachito on the corner of Pellegrini and Maipú in Rosario, the owner Rubén Ramírez put ketchup inside a ham-and-cheese toasted sandwich and gave the result a name. That single condiment is the whole difference between a Carlito and the ordinary tostado sold in every café in Argentina, and Rosario has spent seventy years insisting the difference matters enough to defend it by law.

Strip it to parts and it could not be simpler. Two slices of pan de miga, the soft crustless white bread Argentines use for pressed sandwiches, get a thin coat of butter on the outside faces. Inside go ham, a cheese that melts cleanly, and the line of ketchup. The sandwich is closed, pressed flat in a toaster or on a plancha until the outside is gold and crisp and the cheese has gone to liquid, then cut corner to corner into triangles and served hot enough to string.

The ketchup is the part everything turns on, and it is also the part that goes wrong. Too much and it floods the melted cheese, turning the centre sweet and loose so the triangle sags and slides apart in the hand. Too little and it reads as nothing, and the sandwich collapses back into a plain tostado with a faint memory of tomato. Pan de miga with no crust has no structure of its own; it depends entirely on the press and the toast to set into something that holds, and a Carlito pulled too soon is a damp folded thing rather than a crisp one.

It is bar food, and it eats like bar food. The triangles come out small and very hot, the cheese pulling in threads when you lift one and the buttered crust crackling against the teeth, the ketchup a sweet-sour note running under the salt of the ham. It is the thing you order at a chopería with a cold beer in the afternoon, two or three triangles to a plate, designed to be eaten with one hand while the other holds the glass.

In Rosario the word has eaten the category. Order a tostado in the city and what tends to arrive is a Carlito, ketchup and all, because the local default simply absorbed the addition decades ago; the rest of Argentina keeps tostado and Carlito as separate orders. It shows up in choperías, in football-club buffets and at kiosks near the schools, priced as the cheapest hot thing on the board, the sandwich a Rosarino reaches for without thinking.

Rosario keeps a careful line around what counts. The plain tostado, butter and ham and cheese with no ketchup, is the parent and not the Carlito. The Carlito especial, loaded with chicken or beef, peppers, olives, onion and egg, is sold everywhere in the city but is regarded by purists as a different and busier sandwich that has left the original behind. The point of a Carlito, as Rosario tells it, is that it is the small austere version with exactly one surprise in it, and that adding more is a way of losing the thing.

The name is the one part the record cannot fully settle. The likeliest account is that Ramírez liked the sandwich enough to christen it after the name he meant to give a son; a rival and fonder story ties it to the tango singer Carlos Gardel, who spent formative years in the city. Rosario tends to keep both stories in circulation, which suits a sandwich that the city treats as folklore as much as food.

How Rosario Made a Sandwich Official

The creation is unusually well fixed for a café sandwich. Cachito, the family bar where the Carlito was born, stood at Pellegrini and Maipú and stayed open until 1975; Rubén Ramírez is named as the man who first put the ketchup in, in 1953. The sandwich spread bar to bar across Rosario through the following decades until it was simply what a tostado meant in that city, ketchup included, with no one needing the backstory to order one.

The name carries two competing origins and the honest version keeps them apart. One holds that Ramírez named it for the son he intended to call Carlito; the other reaches for Carlos Gardel, whose myth Rosario shares with several other cities. Neither is documented in a way that closes the question, and the diminutive Carlito, singular, is how the city says it, the trailing s of Carlitos being the outsider's spelling.

From Cachito the sandwich travelled the only distance it needed to, bar to bar across one city, never quite becoming a national dish the way the choripán or the lomito did. That local containment is part of why Rosario claims it so fiercely: the Carlito stayed Rosarino while plenty of Argentine foods went everywhere, and the city kept a sandwich that was recognisably its own.

The hardest date in the account is also the most recent. In 2014 the Concejo Municipal of Rosario, on a proposal from the councillor Carlos Comi, formally declared the Carlito part of the city's cultural and gastronomic heritage, putting a ham-and-cheese toasted sandwich with ketchup on the municipal register beside monuments and landmarks.
