Cinnamon Roulade with Apple Raisin Filling

In a saucepan combine the apples, peeled, cored, and chopped fine, the brown sugar, the butter, and 3/4 cup water, simmer the mixture, stirring occasionally, for 8 to 10 minutes, or until the apples are tender, and stir in the raisins. In a small bowl dissolve the cornstarch in 1/4 cup cold water, add the mixture to the apple mixture, and boil the mixture for 1 minute. Stir in the rum, boil the filling for 1 minute, and let it cool. The filling may be made 1 day in advance and kept covered and chilled.
