Why it works: Sugar and vanilla are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 35,032 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓

Ingredients
Directions
Make the custard base
In a bowl, combine the gelatine with cold water and let it sit for 10 minutes.
Pour boiling water over the gelatine and stir until dissolved.
In another bowl, beat the egg yolks until light.
Heat the gelatine mixture in a skillet until it begins to bubble.
Quickly stir in the egg yolks, stirring constantly to prevent curdling.
Once thickened, remove from heat and strain into a large bowl.
Sweeten with sugar and vanilla, keeping in mind the cream to be added later.
Set and assemble
Allow the mixture to cool and congeal until firm enough to hold a spoon mark.
Gently fold in the whipped cream.
Prepare a sponge cake by cutting off a thick slice from the bottom and hollowing out the inside, leaving a shell.
Pour the mixture into the cake shell, replace the top slice, and refrigerate until ready to serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cox's gelatine
- Sets the liquid mixture into a firm, sliceable structure as it cools.
- Egg yolks
- Thicken the mixture and add richness and a smooth, custard-like texture.
- Whipped cream
- Adds lightness and creamy moisture to the set gelatine mixture.
- Sponge cake
- Forms the edible shell that holds the set mixture in place.
The step that matters
Stirring the egg yolks into the hot gelatine. Egg yolks scramble if they meet high heat too quickly. Adding them off the heat or stirring constantly while adding them keeps the mixture smooth and thickened rather than curdled.
