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 ↓
Mottled Chocolate Cream
Ingredients
Directions
Prepare the gelatine
Soak the gelatin in cold water for at least 1 hour.
Fill a cup with boiling water and keep hot until the gelatin dissolves.
Make the custard
Beat the yolks of the eggs with half of the sugar.
Pour the boiling milk into the beaten yolks.
Cook the mixture until it thickens, stirring constantly.
Beat the egg whites until stiff.
Slowly pour the hot mixture into the stiff egg whites while stirring briskly.
Add the dissolved gelatin and vanilla extract to the mixture.
Divide the mixture in half.
Stir the melted chocolate into one half of the mixture.
Allow both mixtures to cool, stirring occasionally.
Mottle and set
Pour a little of the dark mixture into a mold and let it partially harden.
Add some of the light mixture, repeating until all is used.
Keep the unused mixture warm to prevent hardening.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Gelatin
- Sets the cream so it holds its shape when unmolded.
- Eggs
- Yolks enrich and thicken the custard; whites are beaten to add lightness.
- Milk
- Forms the creamy base of the custard.
- Sugar
- Sweetens the cream and helps stabilise the beaten egg yolks.
- Baker's chocolate
- Gives the dark mottled portion its chocolate flavour and colour.
The step that matters
Slowly pour the hot mixture into the stiff egg whites. Adding hot custard too quickly can deflate the whites and cause them to cook unevenly; pouring slowly while stirring briskly tempers the mixture and keeps it airy.
