Eggnog Mousse

All the flavors of a boozy holiday eggnog transformed into a billowy, spoonable mousse. Egg yolks beaten with sugar over a double boiler, spiked with dark rum and brandy, then folded with whipped cream and stiff egg whites into something impossibly light that melts on the tongue.

The double boiler step is where you build the foundation. Beating the yolks and sugar over hot water cooks them just enough to thicken safely while keeping them fluffy and light. The gelatin, softened in rum and brandy, goes in while everything is still warm so it dissolves completely and sets evenly as the mousse chills.

Folding is everything here. The whipped cream goes in first and gets mixed thoroughly into the chilled gelatin base. Then the egg whites get folded in gently with a light hand so you don’t deflate all that air you just whipped into them. Those whites are what give the mousse its cloudlike texture.

Freshly grated nutmeg is a must. Pre-ground nutmeg tastes dusty and flat compared to the warm, almost piney aroma of freshly grated. One and a half teaspoons is generous, and that’s what makes this taste like real eggnog instead of vanilla pudding.

Chef Tips

• Chill the gelatin mixture for exactly 10 minutes before folding in the cream. Too warm and it won’t set; too cold and it turns lumpy.
• Whip the egg whites to firm peaks, not stiff. Over-whipped whites are grainy and don’t fold smoothly.
• The 4-6 hour chill time is not negotiable. The gelatin needs that time to fully set the mousse.
• Crush peppermint candies right before garnishing so they stay crunchy and don’t dissolve into the mousse.

Variations

• Non-alcoholic: Replace the rum and brandy with rum extract and a splash of apple cider for the liquid.
• Chocolate eggnog: Fold in a few tablespoons of cocoa powder with the whipped cream for a chocolate-eggnog hybrid.
• Individual servings: Set the mousse in wine glasses or ramekins for an elegant plated holiday dessert.
