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 ↓

Cook over medium heat until thickened.
Beat egg with sugar in a bowl until well combined.

Sugar and vanilla barely smell alike, yet cooks put them together in 35,032 recipes: they work on texture and structure more than aroma.
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 thickens into a smooth, pourable cream.
- Flour
- Thickens the milk as it heats, giving the filling body and structure.
- Butter
- Adds richness and a softer, creamier mouthfeel to the filling.
- Egg
- Sets when heated, further thickening the cream and giving it a custard-like texture.
- Sugar
- Sweetens the filling and helps balance its richness.
The step that matters
Adding the egg mixture to the sauce. If the hot sauce is added to the egg too quickly, or the egg is not stirred in slowly, the egg can scramble into lumps. Stirring it in slowly while the sauce is warm lets the egg mix evenly and set smoothly as it cooks.
Swap the vanilla
How well each one fits the dish's main ingredients (milk, flour, butter, egg, sugar):
- Vanillathe original
- Raisinfits about as well
- Figfits less well
- Coconutfits less well
Fit is the average pairing score against milk, flour, butter, egg, sugar. Candidates are from the same food group and used in at least 100 recipes.
