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
- Corn starch
- Thickens the milk into a smooth, sliceable custard filling as it heats.
- Egg
- Adds richness and helps set the custard; the white is whipped for the meringue topping.
- Milk
- Forms the liquid base of the custard filling.
- Sugar
- Sweetens the filling and helps the meringue whip and hold its peaks.
The step that matters
Stir the corn starch paste into the hot milk. Corn starch thickens only when heated, and lumps form if it is added as dry powder. Mixing it first into a smooth paste with cool milk lets the starch disperse evenly, so the custard thickens without clumps.
