Butterscotch Pudding

1/4 cup cornstarch 2/3 cup firmly packed light brown sugar 3 cups low-fat milk 1/4 tsp salt 1 large egg 1 tblsp unsalted butter 1 tsp vanilla extract 3 tblsps whipped cream  In a small bowl,whisk together the cornstarch, 1/3 cup of the brown sugar, and 1/2 cup of the milk. In a medium saucepan, combine the remaining 21/2 cups milk, the remaining 1/3 cup brown sugar, and the salt. Bring to a boil over medium heat. Stir the cornstarch mixture into the boiling milk mixture and cook, stirring, until thickened, about 4 minutes. In a small bowl, lightly beat the egg. Gradually whisk some of the hot milk mixture into the egg, then whisk the warmed egg mixture back into the saucepan. Return to the heat and cook, whisking constantly, for about 1 minute. Remove from the heat and stir in butter and vanilla. Spoon into 4 desert bowls and refrigerate until chilled, about 1 hour. With a #21 star tip and a pastry bag, pipe the whipped cream on top of the pudding (or use a spoon to form small dollops) and serve. Helpful hint: Mixing the cornstarch with a small amount of milk helps prevent the cornstarch from forming lumps when it's added to the hot milk. Serves 4 Working time: 15 min.
