In a saucepan, over medium heat, whisk the cream, cornstarch, brown sugar and cane syrup together. Cook for 10 to 12 minutes, or until a light custard forms. Stir in the chocolate and mix well. Place a piece of plastic wrap directly on top of the custard. Cool completely. Fold in half of the crushed pralines. Pour the custard into the pie shell. Sprinkle the top with the remaining pralines. Refrigerate for 4 hours before serving. Serve each slice with whipped cream and a drizzle of Caramel Sauce.
