In a large saucepan, add milk, heavy whipping cream, and mulling spices.

Mix well and then cover. Cook on medium/low heat to a simmer. 

Next, while this is coming to a simmer, prepare the egg mixture. 

Like I mentioned I prefer using a blender for this. I used my Ninja. 

In a blender mix egg, pulse, then add in sugar and pulse again to mix well.

Once prepared it's time to add to milk mixture. You are going to temper the eggs. 

Remove lid, stir one more time, then add the egg, a little at a time (tempering), stirring constantly, until the entire mixture of an egg is added to milk mixture. 

Now, whisk constantly or stir and then temp read the mixture, you want 160° and no higher, then remove from heat. 

Place the strainer over the bowl, and pour the mixture through a strainer.

Make sure to use a bowl that is big enough to support the strainer and liquid. 

Add in rum and vanilla extract.  (at this point if you are going to make it alcoholic, you can add in a few shots of your favorite spirits. )

Serve warm or allow to chill.

Pour into glasses or mugs, top with whipped cream and a dusting of nutmeg. 

ENJOY!
