A sopaipilla, sopapilla, sopaipa, or cachanga is a kind of fried pastry and a type of quick bread served in several regions with Spanish heritage in the Americas. The word sopaipilla is the diminutive of sopaipa, a word that entered Spanish from the Mozarabic language of Al-Andalus. The original Mozarabic word Xopaipa was used to mean bread soaked in oil. The word is derived in turn from the Germanic word suppa, which meant bread soaked in liquid.
