Why it works: Bread and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Forms the liquid base of the soup and softens the bread as it simmers.
- Egg yolks
- Thicken the soup gently and add richness when stirred in.
- Bread
- Absorbs the hot milk and becomes soft, giving the soup body.
- Moist sugar
- Adds sweetness and a mild caramel flavor to the milk.
The step that matters
Stirring the egg mixture into the soup. Egg yolks thicken when heated gently but can scramble if the soup is too hot or boiling when they are added. Mixing them first with a little warm milk helps them blend smoothly.
Swap the cinnamon
How well each one fits the dish's main ingredients (milk, sugar, bread, egg, butter):
- Cinnamonthe original
- Nutmegfits about as well
- Parsleyfits less well
- Capersfits less well
Fit is the average pairing score against milk, sugar, bread, egg, butter. Candidates are from the same food group and used in at least 100 recipes.
