In Lima, every special occasion—whether it’s a birthday, anniversary, graduation, Christmas, New Year’s or Peruvian Independence day—calls for pisco cocktails. Some of these celebratory drinks, like the Pisco Sour, are well-known around the world. But others, like the Coctel de Algarrobina—an eggnog-like drink spiked with aguardiente—mostly remain a local tradition. I, however, think they deserve recognition. The Coctel de Algarrobina originated in Piura, a city 600 miles north of Lima.
