Churros are fried until they become crunchy, and may be sprinkled with sugar. The surface of a churro is ridged due to having been piped from a churrera, a syringe-like tool with a star-shaped nozzle. Churros are generally prisms in shape, and may be straight, curled or spirally twisted.
Like pretzels, churros are sold by street vendors, who may fry them freshly on the street stand and sell them hot. In Spain and much of Latin America, churros are available in cafes for breakfast, although they may be eaten throughout the day as a snack. Specialized churrerías, in the form of a shop or a trailer, can be found during the holiday period. In addition, countries like Colombia, Peru, Spain, and Venezuela have churrerías throughout their streets. In Portugal, they are commonly eaten at carnivals, fairs and other celebrations, where they are made freshly at street stands.
The dough is a mixture of flour, water and salt. Some versions are made of potato dough. Depending on the recipe, it may not be vegan, they can contain butter, milk or eggs.
