Why it works: Sugar and chocolate are a kitchen classic. They rank in the top 13% of all ingredient pairs, and cooks put them together in 15,404 recipes. Both carry guaiacol, which smells smoky, sweet. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Coagulate when heated, setting the custard into a firm but tender structure.
- Milk
- Supplies the liquid that sets with the eggs into a soft, creamy texture.
- Sugar
- Adds sweetness and softens the flavour of the set custard.
The step that matters
Steam until firm, over gently boiling water. Egg proteins set as they heat, and excess heat makes them tighten further, causing the custard to become rubbery, curdled or weep liquid. Gentle heat keeps the texture smooth and even.
Swap the nutmeg
How well each one fits the dish's main ingredients (milk, egg, sugar, chocolate):
- Cinnamonfits better
- Nutmegthe original
- Gingerfits less well
- Peppermintfits less well
Fit is the average pairing score against milk, egg, sugar, chocolate. Candidates are from the same food group and used in at least 100 recipes.
