Tarte Tatin originated in which country?

Tarte Tatin originated in France.

This upside-down caramelized-apple tart is associated with the Hôtel Tatin in Lamotte-Beuvron, in France’s Sologne region. It is named after sisters Stéphanie and Caroline Tatin, who ran the hotel in the late 19th and early 20th centuries.

The popular origin story says Stéphanie accidentally left apples cooking in butter and sugar too long, then put pastry over them and baked the tart before turning it out. Historians treat that account cautiously: upside-down fruit tarts existed earlier, and the sisters may have popularized a regional preparation rather than invented the form from nothing.

Tarte Tatin is often confused with ordinary apple pie. In a standard pie, pastry usually surrounds or covers the filling; in tarte Tatin, the apples caramelize beneath the pastry during baking, and the finished tart is inverted for serving. It can also be made with pears, quinces, peaches, tomatoes, or onions.
