This delectable breakfast pastry owes its name to its unusual curvy shape. Once upon a time, Spanish shepherds stuck high in the mountains for days on end became desperate for a treat. Using the limited available ingredients of butter, eggs and flour, they concocted a fried pastry that resembled the horns of the sheep they tended. Those sheep were called churros. In time, that humble shepherds' food made its way to Latin America and then north to the United States. In recent decades, Americans have taken to churros with gusto. Dusted with sugar and served with a steaming cup of hot chocolate, churros make an amazing sidewalk breakfast.
