Choripán

The street-food companion of asado, codified at football stadiums and roadside grills in Buenos Aires through the early 20th century. The name is a portmanteau: chorizo + pan (bread). It became the default working-class lunch by the 1950s and the post-game food of choice for River Plate and Boca Juniors crowds. There is no fixed recipe — the chorizo spice mix and the chimichurri vary by stand.

Buenos Aires stadium-and-roadside food fixed by the 1950s; the name is just chorizo + pan. River Plate and Boca crowds eat it standing. Butterflying the sausage doubles the crisp surface and keeps the casing snappy.

A grilled chorizo, butterflied open lengthwise so the cut sides crisp, tucked into a crusty roll with chimichurri spooned over. Eaten standing, often with a beer. The bun must be sturdy enough to hold the grease without going soft — a sub roll, not a hot dog bun. Bite gets sausage snap, smoke, and the raw garlic-vinegar shock of chimichurri all at once.

Butterflying the sausage doubles the crisp surface area and shortens cook time so the casing stays snappy instead of leathery. Chimichurri's job is acid plus raw allium against the rich pork — without it, the sandwich is just sausage in bread. Good chimichurri rests at least an hour so the parsley, garlic, oregano, and vinegar marry; fresh-mixed tastes harsh and grassy.
