Barquillo is a crispy rolled wafer pastry originating in Spain. It is made from the basic cookie ingredients of flour, sugar, egg whites and butter rolled out thinly and then shaped into a hollow cylinder or a cone. It was traditionally sold by roadside vendors known as barquilleros who carried a characteristic red roulette tin (the ruleta de barquillero). It was introduced to Latin America and the Philippines during colonial times. In Spain and former Spanish colonies, barquillos are commonly regarded as a type of Christmas cookie. It is also popular during various fiestas. It spread to neighboring countries and today is extremely popular in East and Southeast Asian countries.
