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 the croutons
Heat 1 inch of fat in a frying pan until boiling.
Drop enough bread squares into the fat to cover the surface.
Fry until browned, then remove with a skimmer and drain.
Serve
Add the croutons to hot soup and serve.
Bake the alternative
For an alternative method, butter thin slices of bread and cut them into ¾ inch squares.
Place the squares in a buttered baking pan, butter side up, and brown in a 400°F (200°C) oven.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

What each ingredient does
- Stale bread
- Its dried-out structure crisps in hot fat or oven rather than turning soggy.
- Fat
- Hot fat conducts heat quickly, browning the bread surface and adding flavour.
- Butter
- Butter adds richness and helps the bread brown in the alternative baked method.
The step that matters
Drain the croutons promptly after frying. Bread keeps cooking from residual heat after it leaves the hot fat, so it can darken too far. As it cools, bread left sitting in fat absorbs grease and loses crispness, so draining it right away keeps it crisp.
