Ingredients:
- 4 large egg yolks (US: Large, UK: Medium), from pasteurized eggs (approx. 80g)
- ½ cup (100g) granulated sugar (US and UK same)
- 2 cups (475ml) whole milk (US and UK same)
- 1 cup (235ml) heavy cream (double cream) (US and UK have heavy cream, double cream is the UK equivalent)
- 1/2 teaspoon ground nutmeg (US and UK same)
- 1/4 teaspoon ground cinnamon (US and UK same)
- Pinch of salt (US and UK same)
- ½ cup (120ml) bourbon, rum, or brandy (or a combination) (US and UK same, though spirit preferences may vary!)
- (Optional) 1/4 cup (60ml) dark rum (for extra depth)
- Freshly grated nutmeg (US and UK same)
- Cinnamon sticks (optional) (US and UK same)
Instructions:
- In a mixing bowl, whisk together the egg yolks and sugar until pale and thickened.
- In a saucepan, combine the milk, cream, nutmeg, cinnamon, and salt. Heat over medium heat until just simmering, stirring occasionally. Do not boil!
- Slowly drizzle about 1/2 cup of the hot milk mixture into the egg yolk mixture, whisking constantly to prevent the eggs from curdling.
- Pour the tempered egg mixture into the saucepan with the remaining milk mixture. Cook over low heat, stirring constantly with a wooden spoon or spatula, until the mixture thickens slightly and coats the back of the spoon. Aim for a temperature of 160°F (71°C) – use a thermometer for best results. Do not boil.
- If desired, strain the eggnog mixture through a fine-mesh sieve to remove any lumps or bits of cooked egg.
- Remove from heat and let cool slightly. Stir in the bourbon (or other spirit of your choice) and the dark rum (if using). Transfer to a pitcher or serving container, cover tightly, and refrigerate for at least 2 hours (or preferably overnight) to allow the flavours to meld.
- Before serving, whisk the eggnog to recombine. Pour into glasses and garnish with freshly grated nutmeg and a cinnamon stick (if desired).
