Enjoy this scrumptious dessert with an ingredient that may be new to you: canned chestnut purée or spread. As an ingredient in desserts, puréed vegetables, meat and poultry sauces, and creamy soups, chestnut purée (made from chestnuts, water and corn syrup) contains no fat, cholesterol or sodium. This rich, classic, unbaked “cake” is for people who like dense, assertive chocolate desserts. It contains canned purée of chestnut flavor with vanilla and sugar from the southwest of France, and this purée is also wonderful served on its own or with ice cream. This is a super-easy dessert, requiring only a few minutes to combine the chestnut, melted chocolate and rum. Extremely rich, the turinois will easily serve eight people.
