Why it works: Hazelnut and rum work together. They rank in the top 12% of all ingredient pairs, and 24 recipes mention both. Both carry 2-methylbutyraldehyde, which smells malty, chocolate. The science ↓

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 the whites lighten the mixture.
- Gelatine
- Sets the mixture so it holds its shape when chilled.
- Milk
- Forms the liquid base of the custard, giving it body and softness.
- Toasted ground hazelnuts
- Add nutty flavour and texture to the set dessert.
- Sugar
- Sweetens the custard and helps balance the rum.
The step that matters
Cooking the custard until thickened. Heating the yolk and milk mixture gently and stirring constantly keeps the eggs from scrambling, while bringing it to thickness lets the yolks set it smoothly. Overheating can curdle the eggs, leaving a grainy texture.

Fit is the average pairing score against cream, milk, egg, hazelnut, sugar, rum. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
