Mantecadas de Astorga

Mantecadas are spongy pastries originating in Spain. Perhaps the best known mantecadas are from Northwestern Spain, being a traditional product of the city of Astorga, province of León, as well as the nearby Maragateria comarca. They taste very much like pound cake. Other Spanish regions also prepare mantecadas. There is a factory producing mantecadas in Sardón de Duero, Valladolid Province and another in Maliaño, Cantabria. The Casa Salinas bakery in Tudela, Navarre, reputed for its excellent mantecadas, closed down in January 2011. Mantecadas are baked in square or rectangular box-shaped paper "cajillas" instead of in the typical muffin round paper cups. The mantecada leaves a characteristic cross-shaped silhouette on the paper when it is removed. In the Alt Maestrat comarca the mantecada square paper cups are known as "caixetes".
