The culinary concept involves caramelizing a sugar crust atop a sweet potato-based custard, drawing inspiration from the classic French dessert. Preparation typically includes baking or pureeing the sweet potato, combining it with ingredients such as cream, eggs, and spices, and then torching a sugar layer to create the characteristic brittle surface.
This application of traditional dessert techniques to a root vegetable offers a novel way to enjoy its nutritional benefits, including high levels of Vitamin A and fiber. The inherent sweetness of the sweet potato complements the caramelized sugar, resulting in a balanced flavor profile. Its emergence reflects a growing interest in creative cooking and the exploration of diverse flavor combinations.
