Add the egg whites to a mixer. Beat the egg whites until frothy, gradually add in 1/3 cup of the sugar and beat till stiff peaks form.
In another bowl beat whipping cream till stiff peaks form.
In yet another bowl beat the egg yolks, add the remaining sugar and beat some more. Add the milk, light cream, rum and Kahlua. Mix well but gently. Slice the vanilla bean lengthwise and scrape the sticky seeds into the mixture. Add the cinnamon and nutmeg. Stir again.
Pour all the ingredients into one big bowl or the bowl you’re going to serve the eggnog.
Gently fold the egg whites and whipping cream into the eggnog and mix thoroughly but very gently. A whisk helps.
Chill and sprinkle with nutmeg or cinnamon when you serve it.
We rimmed our glasses with cinnamon and coarse sugar. It tastes delish when you are drinking the eggnog.
