Pumpkin Nog

Separate the eggs and refrigerate the whites. In a mixing bowl, beat the yolks until creamy. Gradually add in 1/4 pound sugar, beating at high speed until thick. Stir in the rum, milk, pumpkin, vanilla and cinnamon, and chill for at least two hours. Beat the egg whites until soft peaks form. Add the remaining 1/4 pound sugar, beating the egg whites to stiff peaks. Fold the chilled rum mixture into the egg whites. Serve in Martini glasses garnished with a dollop of whipped cream and freshly grated nutmeg.
