Tarte Tatin is a well-known French upside-down tart consisting primarily of apples. One of the popular versions of its modern existence is credited to the two French sisters Carolina and Stephine Tatin who lived in the rural parts of the Loire Valley, France in the 19th century. They ran a restaurant called l’Hotel Tatin and in one of those accidental combined with culinary evolution, her usual recipe of apple tart was placed the wrong way in the oven. She served this ‘unique’ looking dessert warm (without allowing it cool) to her customers and they loved it. They called it the ‘tarte des demoiselles Tatin’ (the tart of two unmarried women named Tatin) and the popular name ‘Tarte Tatin’ was bestowed upon the sisters after their death.
