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, and derived in turn from the Germanic word suppa which meant bread soaked in liquid.
A Sopaipilla is traditionally made from leavened wheat dough (or a mixture of wheat flour and masa harina) to which some shortening or butter is added. After being allowed to rise, the dough is rolled into a sheet that is then cut into circular, square or triangular shapes. The shapes are 8–10 cm in size for the longest dimension (if intended for a dessert) or 15–20 cm (if intended to be stuffed for a main course). The shapes are then deep-fried in oil, sometimes after allowing them to rise further before frying: the frying causes the shapes to puff up, ideally forming a hollow pocket in the center.
