In a small pan, heat the milk and sugar just until it starts to simmer and come to a boil. (see Notes below)
In the meantime, blend the eggs, salt and vanilla.
Once the milk mixture starts to bubble, remove it from the heat and add a small amount of the milk to the egg mixture. Blend immediately. (see Notes below)
Add the rest of the milk to the egg mixture and blend well.
Pour the warm custard into two mugs and sprinkle with nutmeg.
Enjoy!
Notes
Heating: Bringing this just to a boil essentially "cooks" the egg enough that it isn't considered raw any longer.
Adding the Milk: If you add all the milk at once, sometimes the egg will cook too much and you'll end up with little chunks of cooked egg in your custard, which obviously isn't so great. :)
Maple Syrup: If you prefer to use maple syrup instead of sugar, you may. It adds an extra hint of delicious flavor!
