Eggnog ingredients are very similar to ice cream ingredients. You’ve got your cream, milk, sugar and egg yolks. Which led me to, why not just use eggnog, rather than using a whole list of ingredients, making a custard and allowing it time to cool before processing. This is probably the easiest thing I have ever made, next to toast. I love the simplicity of this recipe. And it tastes exactly like eggnog, imagine that =). I thought the eggnog did need a bit more sugar but if you don’t like your ice cream as sweet as I do only add as much as you’d like.
