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 ↓

Ingredients
Directions
Make the custard
Soak the gelatin in the milk for 30 minutes.
Beat the egg yolks with sugar and stir into the milk.
Place the pot in a pan of hot water and stir until the mixture thickens like soft custard.
Set the dessert
Beat the egg whites to stiff peaks and quickly fold them into the mixture.
Pour the mixture into molds and refrigerate until hardened.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Gelatine
- Sets the liquid into a firm, sliceable body as it cools.
- Egg yolks
- Thicken the milk into custard as their proteins gently set with heat.
- Egg whites
- Whipped to stiff peaks, they add an airy, light texture to the set dessert.
- Sugar
- Sweetens the custard and balances the richness of the eggs and milk.
- Milk
- Forms the liquid base that the eggs thicken and the gelatine sets.
The step that matters
Thicken the custard gently in hot water. Egg proteins set with heat, so if the mixture gets too hot it can curdle or turn grainy instead of smoothly thickening. Gentle, steady stirring keeps it silky and lets it thicken evenly before the whites are folded in.
