A sopaipilla, also spelled sopapilla or sopaipa, is a kind of fried pastry and a type of quick bread. The term is applied to three distinct breads, one typical of Central Chile, another of Southern Chile, Uruguay and Argentina, and a third type from New Mexico and Texas in the United States. The word likely comes from the diminutive of the Spanish word sopaipa, which is used to indicate fried dough sweetened with honey.
That word seems to have come from the earlier word "xopaipa", from the Mozarabic "xupaipa", which is a diminutive form of "úppa", "súppa", bread soaked in oil. It could also be from Old Spanish "sopa", food soaked in liquid. However, the term "sopaipa" is almost never encountered in practice in New Mexico, as the diminutive has replaced it in standard usage.
They are sometimes nicknamed "sofa pillows". In Chile sopaipillas are made from wheat flour, lard, pumpkin and salt. In Argentina and Uruguay, a sopaipilla, called torta frita, is a tortilla made from wheat or corn flour and fried in animal fat or roasted in the ashes in a traditional horno.
It may be sweetened spreading Dulce de Leche over the torta frita.[citation needed] In Chile, they are fried and made from pumpkin or squash based dough called zapallo.
