Creamy Eggnog Truffles: The “Holiday Lipid” Perfection

The Chemistry of the Ganache

These truffles are a seasonal twist on a classic ganache, which is a stable emulsion of chocolate and fat. By replacing standard heavy cream with eggnog, we introduce two unique elements: egg yolks (natural emulsifiers) and nutmeg (a warming phenol). Dark chocolate acts as the “anchor,” its bitterness cutting through the high sugar content and rich mouthfeel of the eggnog, resulting in a truffle that melts at exactly 37°C (98.6°F)—your body temperature.

Ingredients List

The Dark Chocolate Shell & Core:
- Dark Chocolate (8 oz): At least 60% to 70% cocoa solids, finely chopped.
The Eggnog Infusion:
- High-Quality Eggnog (21 cup): Full-fat, store-bought or homemade.
- Unsalted Butter (1 tbsp): Softened.
- Ground Nutmeg (41 tsp) & Cinnamon (81 tsp).
- Dark Rum or Bourbon (1 tsp): Optional, for that authentic holiday “kick.”
The Coating:
- Cocoa Powder or Extra Melted Dark Chocolate.
- Pinch of Sea Salt.

Timing: The “Slow-Set” Success

Total time investment: 2 hours and 20 minutes.

Prep: 10 minutes.
Infusing & Mixing: 10 minutes.
Chilling (The Set): 2 hours.

Step-by-Step Instructions

Step 1: The Gentle Heat

In a small saucepan, bring the eggnog and butter to a gentle simmer over medium-low heat.

Actionable Advice: Do not let the eggnog boil. Because eggnog contains eggs and sugar, boiling can cause it to “scald” or curdle, which will ruin the silky texture of your ganache.

Step 2: The Emulsion

Place the chopped dark chocolate in a heat-proof bowl. Pour the hot eggnog mixture over the chocolate. Let it sit for 3 minutes untouched. This allows the heat to penetrate the center of the chocolate pieces.

Step 3: The Whisk

Gently whisk from the center outward until the mixture is glossy and uniform. Stir in the nutmeg, cinnamon, and rum.

Expert Insight: If the mixture looks “broken” or oily, add one teaspoon of room-temperature eggnog and whisk vigorously to re-bind the emulsion.

Step 4: The Long Chill

Cover the ganache with plastic wrap, pressing the wrap directly onto the surface to prevent a “skin” from forming. Refrigerate for at least 2 hours until firm.

Step 5: The Hand-Rolling

Use a teaspoon or small scoop to portion the ganache. Roll into 1-inch balls between your palms.

Pro Tip: If your hands are warm, the truffles will melt. Rinse your hands in ice-cold water and dry them thoroughly before rolling to keep the chocolate firm.

Common Mistakes to Avoid

Using Milk Chocolate: Eggnog is already very sweet. Using milk chocolate (30−40% cocoa) will result in a truffle that is cloyingly sweet and won’t set as firmly as dark chocolate.
Skipping the Nutmeg: Most of what we perceive as “eggnog flavor” is actually the aroma of nutmeg. Be generous with the spice!
Wet Hands: Ensure no water touches your chocolate during the melting process. Even one drop of water can cause the chocolate to “seize,” turning it into a gritty, unworkable paste.

Serving Suggestion

Dust half the truffles in cocoa powder and the other half in a mixture of powdered sugar and nutmeg for a beautiful visual contrast on your holiday dessert board.
