I present to you a step by step guide to concocting you very own little glass of eggnog!
You are going to need about 1 oz. of heavy cream.
Grab yourself 1/2 oz. of simple syrup.
Pour those into a shaker and dry shake (meaning without ice) for a couple minutes. This is basically whipping the heavy cream, like you used to attempt to do with half and half packets in Denny's.
Separate an egg yolk (not sure why I have two pictured) and throw that into the mix. Throw out that stupid leftover egg white.
You had better believe there is booze involved. Toss in 1 1/2 oz. of either rum, brandy, or bourbon. You can always use more if you desire, because it's your liver not mine.
Grate a pinch some fresh (must be fresh) nutmeg in there,
and also a little cinnamon. Do one last dry shake to mix up that wonderful yolk and rum, and then add ice to the shaker and perform the final shake!
Strain all of this into your preferred drinking vessel. Some use a martini glass but I like these little punch bowl glasses with tiny handles. And finally, never forget to grate some more nutmeg over the top. Cheers!
