Picarones are a Peruvian dessert that originated in Lima during the viceroyalty. It is somewhat similar to buñuelos, a type of doughnut brought to the colonies by Spanish conquistadors. Its principal ingredients are squash and sweet potato. It is served in a doughnut form and covered with syrup, made from chancaca. It is traditional to serve picarones when people prepare anticuchos, another traditional Peruvian dish.
