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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Their proteins set as the custard heats, thickening the sauce.
- Milk
- Forms the liquid base that gives the sauce its body and creaminess.
- Powdered sugar
- Adds sweetness and dissolves easily into the warm custard.
- Brandy
- Adds aroma and a warm, spirited flavor.
The step that matters
Stir until it begins to thicken. Egg proteins thicken the custard as they gently heat. If the mixture gets too hot or is not stirred, the eggs can scramble or curdle, so gentle heat over simmering water and constant stirring keep it smooth.
Swap the nutmeg
How well each one fits the dish's main ingredients (milk, egg, brandy, sugar, vanilla):
- Cinnamonfits better
- Nutmegthe original
- Clovefits less well
- Peppermintfits less well
Fit is the average pairing score against milk, egg, brandy, sugar, vanilla. Candidates are from the same food group and used in at least 100 recipes.
