Why not try whipping up a batch of it at home to suit it to your own tastes? That way, you can play with the flavors (and add as much booze as you please). Check out the recipes below and find the one that suits your palate best.
Classic Eggnog (Simple Bites) - This standard recipe calls for raw egg yolks and advises using the freshest eggs you can find, preferably from a local farm.
Coconut Eggnog (Sunset magazine) - I love the addition of coconut milk in this recipe. If you're not a fan of overly sweet stuff, though, go easy on the sweetened condensed milk.
Butterscotch Eggnog (NY Times) - Another take on the classic, containing dark brown sugar and Scotch whisky.
"Coquito" and "Choquito", Puerto Rican Eggnog (The Kitchn) - Two more versions of eggnog that contain coconut milk; one has rum and the other is unleaded and utilizes cream of coconut as well.
"Rompope", Mexican Eggnog (Sweet Life Bake) - This south of the border version of eggnog also uses rum, but utilizes canela (Mexican cinnamon stick) for a regional twist.
Vegan Eggnog (Elana's Pantry) - Now even those who don't consume animal products can enjoy this festive drink. This recipe uses blended up almonds to create the thick texture and agave nectar in place of sugar.
Amaretto Spiked Eggnog Latte (Back to Her Roots) - An egg-free latte version with — you guessed it — nutty Amaretto liqueur.
