Tarte à la bouillie is a traditional Cajun dessert hailing from Louisiana. This French-inspired tart is made with a combination of sugar, salt, flour, milk, whipping cream, eggs, butter, and vanilla. The custard is placed into a pie shell, the crust is brushed with egg whites, and the tart is then baked until the crust becomes golden brown and the center of the filling is slightly jiggly.
