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 boiling fat in a frying pan.
Drop enough half-inch bread squares 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 the croutons
Butter thin slices of bread, cut into three-fourths inch squares, and place in a buttered baking pan, buttered side up.
Brown in a 400 °F (200 °C) oven.

What each ingredient does
- Bread
- Its starch dries and crisps in hot fat or the oven, giving the croutons a crunchy texture.
- Butter
- Adds richness and helps the bread brown evenly in the oven.
- Fat
- Conducts heat quickly, frying the bread to a crisp, browned surface.
The step that matters
Fry until browned, then drain. Bread keeps darkening after it leaves the hot fat, so croutons pulled at deep brown can turn bitter. Stop when they are golden, because browning is driven by heat and time.
