It is an omelette made with eggs and potatoes, sometimes also fried in oil and often served cold as an appetizer. It is part of the cuisine of Spain.

The first reference to the dish is believed to have been found in an anonymous letter addressed to the court of Navarre dating from 1817. The letter details the poor conditions of the populations around Pamplona and the Ribeira, stating that many make do with only a few eggs cooked as a tortilla with potato, breadcrumbs and other simple ingredients to feed five or six people. One popular tale states that it was an army general called Tomás de Zumalacárregui who first invented the dish as a cheap and easy way to feed his troupes during the siege of Bilbao, and yet another version of the story states that it was in fact a poor farmwife who invented the dish, one day when the general visited their farm and requested to be fed.
