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
- Milk
- Forms the liquid base that the flour and egg thicken into a smooth custard.
- Egg
- Its proteins set when heated, thickening the filling and adding richness.
- Flour
- Its starch swells with heat, thickening the custard so it holds its body.
- Sugar
- Adds sweetness and balances the flavour of the custard.
- Vanilla
- Adds a warm aroma that gives the filling its characteristic flavour.
The step that matters
Pour the hot milk onto the beaten egg.. Adding hot milk gradually to the egg, a step called tempering, warms the egg slowly so it does not scramble. Pouring it in all at once can curdle the mixture.
Swap the vanilla
How well each one fits the dish's main ingredients (milk, sugar, flour, egg):
- Vanillathe original
- Raisinfits about as well
- Figfits less well
- Blueberryfits less well
Fit is the average pairing score against milk, sugar, flour, egg. Candidates are from the same food group and used in at least 100 recipes.
