1-First, whisk the 6 large egg yolks and 1/2 cup sugar together in a medium bowl until the mixture is light and creamy. This step builds the base’s richness and sweetness.

2-Next, in a saucepan over medium-high heat, combine 1 cup heavy cream, 2 cups milk, 1/2 teaspoon ground nutmeg, and a pinch of salt, stirring until just simmering to infuse the flavors.

3-Slowly temper the eggs by whisking in the hot milk mixture one spoonful at a time, preventing any curdling and ensuring a smooth texture.

4-Return the egg mixture to the saucepan and cook while whisking constantly until it thickens slightly and reaches about 160°F (71°C) for safety and creaminess.

5-Remove from heat, then stir in the 1/4 teaspoon vanilla extract and optional 1/4 cup brandy, bourbon, rum, or whisky if desired, to enhance the flavor.

6-Strain the mixture through a fine mesh strainer into a pitcher, cover with plastic wrap, and refrigerate until chilled. The eggnog will thicken as it cools, and for a smoother consistency, blend with 1 to 2 tablespoons of milk before serving.

7-Finally, serve topped with whipped cream and a sprinkle of extra nutmeg or cinnamon for that festive touch.
