A churro is a fried dough pastry that originated in Spain and is popular in many countries around the world. It is typically made from a batter consisting of flour, water, sugar, yeast or baking powder, salt, and flavorings such as vanilla extract or cinnamon. The dough is piped into long, thin strips which are then cut into pieces and deep-fried until crispy on the outside and tender on the inside. Churros can be enjoyed plain or topped with sugar, cinnamon, or other sweet toppings such as chocolate sauce or dulce de leche. They are often served as a snack or dessert and are popular at fairs, carnivals, and festivals.
