Picarones are Lima's favourite street sweet, fried to order at stalls in the parks and outside churches, especially in October during the Señor de los Milagros processions. The light, chewy rings are made from a yeasted dough of sweet potato and squash, scented with anise, fried until crisp and drenched in miel de chancaca, a dark syrup of unrefined cane sugar with orange peel, cinnamon and cloves. They are eaten hot, straight from the oil, with plenty of syrup. Chancaca is sold in Latin shops; dark muscovado or piloncillo makes a very good syrup too. Chef's tip: the dough should be very soft and sticky, like a thick batter; resist adding more flour, or the picarones turn heavy and bready.
