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
Prepare the base
Soak the isinglass in cold water for 2 hours.
In a double boiler, heat the milk until scalded.
Beat the egg yolks and mix in the sugar.
Pour the hot milk over the egg yolks and sugar, stirring well.
Make the custard
Return the mixture to the double boiler, drain the isinglass, and add it to the milk mixture, stirring until it thickens.
Stir in the vanilla extract and let it cool until partially set.
Whisk the egg whites until stiff and fold them into the custard.
Mold and serve
Pour the mixture into molds rinsed with cold water and place them on ice.
To serve, loosen the edges, invert onto a small platter, and gently shake to release.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Forms the creamy body of the custard once heated and thickened.
- Eggs
- Yolks thicken and enrich the custard; whites are whipped to add lightness.
- Isinglass
- Gelatin-like setting agent that firms the cream so it holds its molded shape.
- Sugar
- Sweetens the cream and helps balance the richness of the eggs and milk.
The step that matters
Adding the isinglass and stirring until it thickens. Isinglass must be fully dissolved and evenly distributed in warm custard, or it will set unevenly. Heating the egg mixture gently, while stirring, keeps the yolks from scrambling as the mixture thickens and sets.
