In the bowl of a stand mixer fitted with the whisk attachment, whip the egg yolks and sugar together until thick and pale and mixture runs off whisk in a ribbon.

While the eggs mix, stir together the dairy, booze, and vanilla in a large pitcher.

With mixer on low, slowly pour in liquid, increasing speed to medium-low and mixing until just combined. Scrape the sides and bottom of the bowl to ensure there’s no eggs or sugar sitting at the bottom. Stir in nutmeg before pouring into jars.

Close tightly and let sit in fridge for at least two weeks before gifting/serving. Shake well and top with a sprinkle of nutmeg, if desired, before serving.
