In a large mixing bowl, vigorously beat the eggs together with the granulated sugar until the mixture is pale, fluffy, and slightly thickened, forming a luscious base for your eggnog.
In a medium saucepan set over medium heat, carefully combine the whole milk, heavy cream, ground cinnamon, nutmeg, and ginger. Stir the mixture occasionally, allowing it to heat up gently until it is warm but not boiling—this helps meld the flavors beautifully.
Once the milk and spice mixture is warmed, remove it from the heat. Slowly pour the warm mixture into the egg and sugar blend in a thin stream while whisking continuously. This gradual process is crucial for tempering the eggs and achieving a smooth consistency.
After the two mixtures are well combined, return the saucepan to low heat. Cook, stirring constantly, until the mixture thickens slightly and reaches a temperature of about 160°F (71°C). Remember, do not let it boil, as this can curdle the eggs.
Once thickened, remove the saucepan from the heat and stir in the pure vanilla extract and cinnamon syrup. Mix thoroughly to infuse the flavors, then allow your eggnog to cool to room temperature, letting the spices deepen.
After cooling, pour the eggnog into a beautiful serving pitcher and place it in the refrigerator for at least 2 hours or ideally overnight. This chilling step enhances the flavors and ensures a refreshing serving.
When ready to serve, pour the chilled eggnog into festive glasses. Top each serving with a generous dollop of whipped cream, and finish with a light dusting of ground cinnamon and nutmeg for an extra touch of holiday cheer.
