This is one of my very favorite homemade eggnog recipes. We halved the recipe for just two of us to enjoy over a snowy evening at home, and it was just delightful. We didn't have any heavy cream on hand when we impulsively decided to prepare this, so we substituted the cream with sweetened condensed milk, which, since it comes out of the can thickened, was an appropriate consistency, I think.
I was snowed in Friday with no chance of going to work, which seemed to be the universe's way of telling me to comfort myself with eggnog. I made a half recipe and (slap my hand) drank almost all of it myself over the course of the day (after chilling a couple hours, so none before noon at least). This is primo spiked eggnog, very smooth, and should be a great hit at a holiday party!
