1Beat 8 egg yolks with 3/4 cup sugar until light. Meanwhile, scald 2 cups milk and 2 cups heavy cream.
2Beat a little of the hot cream mix into the yolks to temper them, then add rest of the cream to the yolks. Heat in a nonreactive pot until the mixture visibly thickens at about 165°F. Do not boil.
3Remove from the heat and whisk in 1 1/2 teaspoons freshly ground nutmeg, 1/2 teaspoon ground mace, a pinch of ground cloves, 1/4 cup bourbon, and 1/4 cup dark rum. Serve in small punch cups and top with freshly grated nutmeg.
