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
Beat the egg yolks with the sugar until smooth.
Boil the milk, then pour it over the egg mixture while stirring.
Cook until it thickens like a custard, then let it cool, stirring occasionally.
Dissolve the gelatin in a little water and add it to the custard while stirring to prevent lumps.
Assemble
Whip the egg whites with the sugar and heavy cream until stiff peaks form.
Fold the whipped mixture into the custard and add vanilla to taste.
Line a round mold with ladyfingers, ensuring no gaps.
Pour the custard into the mold and let it set.
Unmold
If difficult to remove, apply a warm cloth to the bottom of the mold for a few minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks thicken the custard, and whipped whites add lightness to the filling.
- Gelatin
- Sets the custard so the dessert holds its shape when unmolded.
- Heavy cream
- Adds richness and moisture, and whipped cream lightens the filling.
- Sugar
- Sweetens the custard and helps stabilize the whipped egg whites.
- Milk
- Forms the custard base, which thickens when heated with the egg yolks.
- Ladyfingers
- Line the mold, giving the dessert a structural outer edge.
The step that matters
Pouring the boiled milk into the egg mixture. Egg yolk proteins can scramble if they meet very hot liquid all at once. Pouring slowly while stirring spreads the heat evenly, so the custard thickens smoothly instead of curdling.
