Why it works: Milk and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. The science ↓
Boiled Custard Eggnog
Ingredients
Directions
Make the custard
Mix sugar, flour, and salt in a heavy 6-qt saucepan.
Add egg yolks and mix well.
Using a wire whisk, stir the egg mixture and slowly pour in milk and cream.
Cook over low heat, stirring constantly, until the custard thickens and just coats the back of a wooden spoon.
Remove from heat and let cool. The custard will thicken as it cools.
Finish
When cold, stir in vanilla, nutmeg, and whiskey.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the custard as they set with gentle heat and add richness.
- Sugar
- Sweetens the base and helps keep the custard smooth.
- Milk
- Forms the liquid base that the yolks thicken into custard.
- Light cream
- Adds fat for a richer, silkier texture.
- Flour
- Stabilizes the custard so it thickens more reliably and resists curdling.
The step that matters
Cook the custard over low heat. Egg yolks set at a narrow temperature range. Gentle heat with constant stirring thickens the custard evenly, while overheating can scramble the yolks and make the eggnog grainy.
Swap the nutmeg
How well each one fits the dish's main ingredients (sugar, flour, egg, milk, cream, vanilla):
- Cinnamonfits better
- Nutmegthe original
- Peppermintfits less well
- Turmericfits less well
Fit is the average pairing score against sugar, flour, egg, milk, cream, vanilla. Candidates are from the same food group and used in at least 100 recipes.
