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 ↓
Croutons for Soup
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Fry
Heat 1 inch of boiling fat in a frying pan.
Drop enough half‑inch squares of stale bread into the fat to cover the surface.
Fry until browned, then remove with a skimmer and drain.
Add the croutons to hot soup and serve.
Bake
Alternatively, butter thin slices of bread, cut into small squares, and place them in a baking pan, buttered side up.
Brown in a 400°F (200°C) oven.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Stale bread
- Its dried-out structure crisps and browns well, giving croutons a firm, crunchy texture.
- Frying fat
- Conducts heat quickly, browning and crisping the bread surface while keeping its interior tender.
- Butter
- Adds richness and aids browning in the oven, giving the croutons a golden color and nutty flavor.
The step that matters
Keeping the fat hot when adding the bread. Fat must be properly hot before the bread goes in. Adding too many squares at once cools the fat, so the bread soaks up grease instead of searing, leaving croutons soggy and oily rather than crisp.
