Place your serving glasses in the freezer for at least 15 minutes before mixing to keep the cocktail perfectly cold and prevent the eggnog from separating due to heat.

Toast the nutmeg and cinnamon lightly in a dry pan for 30 seconds before sprinkling to release their essential oils and intensify their warm, aromatic flavors.

Combine vodka and coffee liqueur with ice and shake vigorously for 10 seconds before pouring into your glass to properly chill and dilute the spirits slightly for better balance.

Let your eggnog sit out for 10 minutes before topping the drink so it pours smoothly and creates a velvety layer that won't sink or separate from the cold base.

Dust nutmeg and cinnamon on top of the eggnog layer just before serving to create a beautiful presentation and ensure fresh spice flavor with each sip.
