Anticuchos

Andes, Peru (pre-Columbian Quechua tradition; colonial adaptation with beef heart)

Anticuchos are Peru's most beloved street food — beef heart marinated in ají panca (dried dark-red Peruvian chilli), cumin, garlic, vinegar, and spices, threaded onto bamboo skewers, and grilled over charcoal until the exterior chars and the interior remains tender and deeply flavoured. The preparation is pre-Columbian in origin: the Andean Quechua people cooked skewered meat over fire long before Spanish arrival; the colonial period added beef heart (a new protein) and European spices. The heart's dense, intensely beefy muscle has almost no fat and requires acidic marination to tenderise; the ají panca provides a deep, smoky-fruity heat distinct from any European or Asian chilli. Anticuchos are sold at nighttime humo (smoke vendors) across Peru and are associated with football matches, festivals, and late-night eating.

Boiled yellow potato and a creamy ají amarillo sauce alongside are mandatory; the char of the heart against the neutral potato and the fruity-creamy chilli sauce creates one of South America's most considered flavour triangles.
