1. To make the chocolate sauce, heat the cream in a small saucepan over medium heat. Remove the saucepan from the heat and add the chocolate. Let stand a few minutes until the chocolate softens, then whisk until smooth. Whisk in the corn syrup. Transfer to a bowl to cool completely.

2. To make the cherry sauce, cook the cherries and sugar in a saucepan over medium heat, stirring often, until the sugar is dissolved and the cherries give off their juice, about 5 minutes. Sprinkle the cornstarch over the kirsch in a small bowl and stir to dissolve the cornstarch. Stir into the cherries and cook just until the juices thicken. Transfer to another bowl and cool completely. (The chocolate and cherry sauces can be prepared up to 2 days ahead, cooled, covered, and refrigerated. Gently reheat the chocolate sauce just until fluid.)

3. Scoop equal amounts of the ice cream into 4 parfait or martini glasses, adding the chocolate and cherry sauces to get a layered effect. Top each with a dollop of whipped cream and a fresh cherry. Serve immediately.
