Butter for cooking, and for after you have cooked your French toast of course
Instructions
Whisk egg yolks and sugar together in a medium bowl until light and creamy
In a saucepan over medium-high heat, combine cream, milk, nutmeg, cinnamon, clove, and salt. Stir often until the mixture reaches a bare simmer
Add a big spoonful of the hot milk to the egg mixture, whisking vigorously
Repeat, adding a big spoonful at a time, to temper the eggs
Once most of the hot milk has been added to the eggs, pour the mixture back into the saucepan on the stove
Whisk constantly for just a few minutes, until the mixture is just slightly thickened (or until it reaches about 160 degrees F on a thermometer). It will thicken more as it cools
Remove from heat and stir in the vanilla, and alcohol, if using
Pour the eggnog into a bowl and cover with plastic wrap
Refrigerate until chilled. It will thicken as it cools (from 30 min to 24 hours)
Once eggnog is chilled, remove from refrigerator
Preheat griddle to 350 degrees F or heat a skillet over medium heat
Whisk eggnog up to make sure everything is fully mixed
