Buñuelos are a type of fried dough balls that are popular in Valencia, especially during the Fallas festival. They are made from a dough mixture of flour, water, and yeast, which is then deep-fried until golden and crispy. Buñuelos are often dusted with powdered sugar and can be enjoyed plain or filled with various sweet fillings such as chocolate or cream. They are a delightful treat to indulge in while exploring the streets of Valencia.
