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 ↓
After-dinner Croutons
Ingredients
Directions
The book gives no oven temperature. The 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Cut sandwich bread into slices ¼ inch thick.
Cut each slice into four small triangles.
Dry
Dry the triangles in a 300°F (150°C) oven until they are delicately browned.
Serve
Serve them hot or cold.
For serving, spread a mixture of equal parts butter and creamy cheese on the croutons, adding a little minced parsley if desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sandwich bread
- Forms the base that dries into a crisp, crunchy crouton.
- Butter
- Adds fat and richness that carries flavor and softens the spread.
- Creamy cheese
- Adds richness and a tangy flavor to the spread.
The step that matters
Dry the triangles until delicately browned. Low, steady oven heat dries the bread into a crisp crunch. Browning happens quickly at the edges, so the croutons can scorch if left unchecked, and thin pieces brown faster than thick ones.
Swap the parsley
The recipe marks parsley as optional. How well each one fits the dish's main ingredients (bread, butter, cheese):
- Thymefits about as well
- Nutmegfits about as well
- Parsleythe original
- Capersfits about as well
Fit is the average pairing score against bread, butter, cheese. Candidates are from the same food group and used in at least 100 recipes.
