Anticuchos de corazón with vinegar–ají panca marinade and cooked sides
Anticuchos de corazón are beef-heart skewers strongly associated with Peruvian grilling and street-food cooking. The cut is lean and muscular, very different from liver in texture, and it benefits from removing tough exterior membrane before slicing. A marinade based on ají panca, vinegar, garlic and spices gives the recognisable dark-red coating; the grill supplies surface browning rather than replacing the marinating step.
Start with cleaned beef heart from a reputable butcher, trim away visible valves, membrane and thick connective strands, and slice into even pieces. Ají panca is a Peruvian dried-red-chilli paste that adds depth without needing the fierce heat of a hot fresh chilli. The seasoning should coat the meat in the refrigerator; raw marinade is never used as a finishing sauce unless it has been handled by a separately validated process, so none is served here.
There is an important safety distinction between a steak and organ meat. USDA consumer guidance specifies 71 °C for beef heart, higher than the 63 °C plus rest minimum for intact steaks. The centre of a large skewer piece must therefore be measured, even when the outside has grill marks. Cook the potato and choclo before the meat is finished, allowing the skewers to reach the table still hot and the side dishes fully cooked.
