Anticuchos are documented in Peru from at least the Inca period — originally made with llama heart. The beef heart version developed after the Spanish introduced cattle. The street anticucho culture of Lima is associated with Afro-Peruvian communities (descendants of enslaved Africans who were given offal cuts) — the technique of transforming tough, cheap cuts into extraordinary flavour through marinade and fire is a defining expression of this culinary tradition.
Anticuchos — cubes of beef heart marinated in ají panca (the dried, smoky red chilli of Peruvian cooking), vinegar, cumin, and garlic, then grilled over charcoal — is the most important street food preparation in Lima and one of the oldest continuously prepared foods in the Americas. Beef heart's unique characteristics — low fat, high myoglobin, dense muscle fibre — require both the extended marinade (to tenderise and flavour) and the high-heat charcoal grill (to char the surface before the interior overcooks).
