Goes beyond plain old eggnog, doesn't it?
Here is my recipe for a thick, flavorful eggnog. I couldn't find brandy extract at the store, so bought rum extract, and might spike it with some brandy.
Eggnog
1 quart milk
1 cup sugar
4 tablespoons flour
pinch salt
6 eggs, separated
vanilla to taste
brandy extract
1 pint light cream or half-and-half
(rum or brandy to taste)
Heat the milk until tiny bubbles form around the side of the pan. While it's heating, toss the sugar, flour, salt, and egg yolks into the top half of a double boiler and mix them well. When the milk is hot enough, add slowly, stirring constantly. Place over boiling water, and cook, stirring often, until it coats the spoon like a smooth, clingy cream. Take off the heat, add vanilla, set aside to cool. When cool, stir in the light cream or half-and-half; then beat the egg whites until they're stiff, and fold them into the nog. Spike with whatever and garnish with grated nutmeg.
