The origin of the churro is a subject of debate. One theory suggests they were brought to Europe from China by the Portuguese, who adapted the 'Youtiao' (fried dough strips) by giving them a star shape. Another popular theory is that they were invented by Spanish shepherds. Because they worked in high mountains with no access to fresh bread, they developed a simple dough of flour, water, and salt that could be easily fried over an open fire. The name 'Churro' reportedly comes from the 'Churra' breed of sheep, whose horns resemble the fried pastry. In Spain, churros are a breakfast staple, traditionally served with a cup of chocolate so thick it is almost a dip.
