The Tatin sisters, Caroline and Stephanie, were French hoteliers and chefs known for creating the famous Tarte Tatin, a caramelized upside-down apple tart. They ran a small hotel and restaurant in Lamotte-Beuvron, France, during the late 19th century. The dessert was reportedly invented by accident when one sister overcooked apples in butter and sugar, leading to a deliciously unique dish. The Tarte Tatin gained popularity and became a classic French dessert, celebrated for its rich flavors and simple preparation. Today, it is enjoyed worldwide and is often featured in restaurants and cookbooks, showcasing the lasting legacy of the Tatin sisters.
