Cylindrical doughnut-style snacks originated in Spain and named after the curly ridged horns of Churro sheep. In Mexico, churros are a popular street food, usually available in the evening, but also may be found in malls or on the dessert menu at local restaurants. Preparation: the dough is piped into hot oil via a churrera, a large syringe-shaped tool with a star nozzle, and sprinkled with cinnamon sugar.
