 While the word "Lambreado" is a degeneration of the correct "Lampreado" there is little data about the origin of the name of this fried cake made of cassava, known in Paraguay as mandioca, and beef.In Paraguay, a Castilian-Guarani bilingual country, and in Northeastern Argentine (where the Guarani language is also spoken) it is also called "payaguá mascada", an allusion to one of the tribes of the Guarani people ("payaguáes") who populated the Paraguayan geography in pre-Columbian times.There are several varieties of "Lampreado."
