Ingredients:
- 4 large eggs, separated
- 1/2 cup (100g) granulated sugar, plus 1 tablespoon (12.5g)
- 3 cups (710ml) whole milk
- 1 cup (240ml) heavy cream
- 1/4 teaspoon freshly grated nutmeg
- 1/2 teaspoon ground cinnamon
- 1 teaspoon vanilla extract
- Optional: 1/4 - 1/2 cup (60-120ml) dark rum, brandy, or bourbon
Instructions:
- In a heatproof bowl, whisk together egg yolks and 1/2 cup sugar until pale and slightly thickened.
- In a medium saucepan, combine milk, cream, cinnamon, and nutmeg. Heat over medium heat, stirring occasionally, until just simmering. Do not boil!
- Gradually drizzle about 1/2 cup of the hot milk mixture into the egg yolk mixture, whisking constantly. This tempers the eggs, preventing them from scrambling.
- Pour the tempered egg yolk mixture back into the saucepan with the remaining milk mixture. Cook over low heat, stirring constantly with a wooden spoon or heat-resistant spatula, until the mixture thickens enough to coat the back of a spoon (around 170-175°F or 77-79°C). Do not boil!
- Immediately strain the eggnog base through a fine-mesh sieve into a clean bowl to remove any cooked egg bits. Stir in vanilla extract.
- In a clean, dry bowl, whisk egg whites until soft peaks form. Gradually add the remaining 1 tablespoon of sugar and continue whisking until stiff, glossy peaks form.
- Gently fold the whipped egg whites into the cooled eggnog base.
- Stir in rum, brandy, or bourbon, if desired.
- Cover and refrigerate for at least 2 hours, or preferably overnight, to allow the flavours to meld.
- Serve chilled, garnished with freshly grated nutmeg.
