Yemas de San Leandro are egg-yolk sweets cooked in syrup by the Augustinian nuns of Seville's Monasterio de San Leandro, a convent speciality of the city.
The Monasterio de Agustinas de San Leandro is dated to 1295, though the date is disputed, and its nuns make the convent's sweets in the workshop known as the obrador, cooking the yemas and bitter oranges in the same syrup. King Alfonso XIII went to the convent to fetch them in 1929, the year of the Exposicion Iberoamericana. Confiteria La Campana lists yemas sevillanas among its traditional sweets.
