With the mixer on FOLD, add the beaten egg whites. Place in an airtight, glass container and chill several hours, overnight or even up to 1 year. Research has proven Traditional Eggnog is best served aged 1-3 weeks.
When ready to serve, fill a cocktail glass 2/3rd full, grate a little fresh nutmeg on top and serve.
Traditional Eggnog is made with liquor, but it is still delicious without liquor. Add 1 teaspoon vanilla extract and an additional 1/2 cup milk or cream if not adding liquor.
