Making your own eggnog is quite simple and the rich, foamy texture is a vast improvement over anything you can buy at the store.
Preparation Method
Place heavy cream and sugar in the blender. Select a low speed and blend, gradually increasing the speed to HIGH until cream is just whipped, 15-20 seconds. Do not overmix.
Remove about ½ cup of whipped cream from blender, set aside in a bowl and refrigerate.
Add all remaining ingredients to blender and blend on a medium speed until blended, about 15 seconds.
Chill eggnog in refrigerator in blender jar for at least 1 hour.
Just before serving, add reserved whipped cream to blender and PULSE 2 to 3 times.
Pour eggnog into cocktail glasses. Garnish with additional grated nutmeg and serve immediately.
