Why it works: Bread and cheese are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 2,130 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓
Bread-and-cheese Soup
Ingredients
Directions
Make the broth
Combine veal, ham bone, onion, and water in a pot; cook slowly for 4 hours.
Strain the mixture, pressing hard to extract liquid, then cool and remove fat.
Season the broth with pepper and salt; bring to a boil.
Add parsley and corn flour (dissolved in cold water); simmer for 5 minutes.
Make the custard
Heat the milk in a separate pot, pour it over the beaten eggs, and stir constantly until thickened.
Assemble and serve
In a tureen, place the fried bread-dice and grated cheese; pour the milk and egg mixture over them.
Finally, add the hot soup, stir, and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Veal
- Breaks down during slow cooking to give the broth body and savory flavor.
- Eggs
- Thicken the milk mixture as they set with gentle heat, adding richness.
- Dry cheese
- Melts into the hot soup and adds salty, savory flavor.
- Bread-dice
- Soak up liquid and give the soup a soft, substantial texture.
- Corn flour
- Thickens the simmering broth as its starch gelatinizes with heat.
- Milk
- Adds creaminess and softness to the egg mixture.
The step that matters
Stirring the milk and egg mixture until thickened. Eggs set when heated, and if the mixture gets too hot or is not stirred constantly, the proteins can curdle into lumps instead of forming a smooth, thickened custard.
