Caldo de Cabeza

In Quechua, uma means head, and in the central highlands around Junín the soup is known by names like uman caldo (head broth) — though this is a regional name and spelling, not the universal one; most of Peru simply calls it caldo de cabeza. The dish has no documented birthplace or date; it is an old, widespread sierra tradition rather than an invention with an author. Its heartland runs across the highlands — Áncash, Cusco, Puno, Junín, Ayacucho and Cajamarca — where the sheep's head, a cheap and gelatin-rich cut, is turned into a nourishing broth.

The broth is clear-to-cloudy and deeply savory, light on grease but full-bodied, with a faint stickiness on the lips from the gelatin the head gives up. Soft pieces of head meat, chewy kernels of mote and tender potato fill the bowl. A scatter of mint or cilantro lifts it, and a spoon of ají paste turns up the heat. Eaten scalding at dawn against the cold and the morning after, it is plain, warming and quietly restorative.

The whole point is a long, gentle simmer drawing body from the head. A sheep's head is dense in skin, cartilage and the connective tissue of the jaw and ears — exactly the parts richest in collagen, which slowly hydrolyzes into gelatin over hours of low heat, giving the broth its silky weight and the lips their faint stick. Marrow and the soft head fat add richness. Because the head gelatinizes faster than heavy beef bones, it does not need an all-day boil; herbs go in near the end so their aroma survives.
