It is widely believed that churros originated in Spain and are regarded as a Spanish dessert.
However, some believe that churros evolved from another dish - Chinese youtiao, which looks confusingly similar to their Spanish counterpart but is served in dry form. According to this version, the Asian delicacy encountered by Portuguese traders was modified by coating it in sugar and such dessert form, spread across Western Europe in the 16th century.
Supporting this theory is that youtiao was created much earlier, as early as the 12th century.
