In a medium saucepan, mix heavy cream, milk, cornstarch, vanilla, nutmeg and salt. Stirring often, bring to a very slight simmer over medium heat.
Temper egg yolks by drizzling the hot milk mixture in to the bowl of yolks and sugar while whisking constantly. Use a ladle to make drizzling easier. After adding about ½ of the hot milk mixture, pour the egg yolk mixture into the saucepan while whisking.
Whisking constantly, cook over medium heat until slightly thickened or 160°F (about 2-3 minutes). It should coat the back of a spoon. Do not bring to a boil.
Strain eggnog through a mesh strainer to remove any bits of egg. Cover and refrigerate.
If desired, blend until smooth with an immersion blender.
Stir before serving to mix up spices that have settled to the bottom. Serve chilled topped with whipped cream and a dusting of cinnamon, if desired.
For an adult beverage, add Southern Comfort whiskey to each cup, to taste.
Notes
Be sure to use heavy whipping cream. Do not substitute for light cream or half-and-half.
This eggnog is extra sweet to balance out any added liquor. If you plan to drink this eggnog without alcohol, consider decreasing the sugar to 1/2 cup.
Cornstarch is added to get a thicker consistency, similar to Southern Comfort Eggnog. Be sure to stop heating your mixture at 160°F or the cornstarch may thicken too much.
Don't have a candy thermometer? At 160°F, the eggnog should coat the back of a spoon.
Consider adding the following liquors: Southern Comfort Whiskey, Spiced Rum, Brandy, Baileys.
Save your egg whites to make an egg white omelette or whisk with 2 whole eggs for scrambled eggs, either for breakfast or with fried rice. Alternatively: use them for meringue cookies or pie or royal icing for sugar cookies.
