Whisk together egg yolks and sugar until smooth. Set aside.
6 egg yolks, ⅔ cup granulated sugar
Heat milk, cream, nutmeg, and salt, in a medium saucepan over medium heat until just beginning to simmer.
2 cups whole milk, 1 cup heavy cream, 1 tsp. ground nutmeg, pinch of salt
Remove from the heat, and add the hot milk mixture to the egg mixture by big spoonfuls, whisking well in between each addition. Be sure to add slowly, we want to temper the eggs.
Once most of the milk mixture is added to the eggs, pour the milk and egg mixture back into the saucepan, and return to the stove.
Heat over medium low until the temperature reaches 160 degrees fahrenheit.
Remove from the heat and stir in vanilla, and alcohol, if desired.
½ tsp. vanilla, 3 ounces spiced rum or bourbon
Strain the mixture through a fine mesh strainer, and pour into a sealable container to store in the refrigerator for up to 2-3 days.
