For many (including Xetheriel), the Holiday season isn't complete without copious amounts of egg nog.  In our house alone, we probably see at least 10L of the stuff pass through our kitchen (into Xeth's mug of course).  Though I haven't been able to develop a taste for it enough to drink that amount, even I like a little bit every so often.  It's also nice with a shot of rum, if you're old enough.  Here are three recipes for egg nog - one uncooked and one cooked (in case you don't like the idea of raw eggs), and one (uncooked) spiked.

Uncooked:

You will need:
2 eggs, beaten well
3 tbsp sugar
2 1/3 cups milk (which kind of milk you use will determine the thickness of your nog)
1 tsp vanilla
dash nutmeg

Combine ingredients in a blender and mix until well-combined and slightly frothy.  If this isn't rich enough for you, substitute 1/3 cup of cream for 1/3 cup of milk.

Cooked:

You will need:
6 eggs
1/4 cup sugar
1/4 tsp. salt (optional)
1 quart milk (4 cups)
1 tsp vanilla 

In a large saucepan, beat together eggs, sugar, and salt.  Stir in 2 cups of the milk.  Cook over low heat, stirring constantly, until the mixture is thick enough to coat a metal spoon, and/or the temperature reaches at least 160ºF.  Remove from heat.
Stir the remaining 2 cups of milk and the vanilla into the mixture.  Cover and refrigerate until chilled.

Extra-rich spiked eggnog:

You will need:
12 eggs, separated
2 cups white sugar
1 750mL bottle white rum
1 quart half-and-half
1 quart heavy (whipping) cream
1 cup sugar
1/4 tsp nutmeg

Combine egg yolks, 2 cups of sugar and rum in a large bowl.  Mix well, cover, and refrigerate for 24 hours. 
Stir half-and-half into yolk mixture.  In a large, chilled bowl, whip heavy cream until soft peaks form; set aside.
In a separate clean bowl, with a clean whisk, whip egg whites until thick, then gradually add 1 cup of sugar until peaks form.  Fold the whipped cream into the egg whites, then fold this mixture into the yolk mixture.  Sprinkle with nutmeg and serve.

Top eggnog with fresh grated nutmeg, cinnamon or grated chocolate.
