Why it works: Bread and egg are a kitchen classic. They rank in the top 13% of all ingredient pairs, and cooks put them together in 22,662 recipes. Both carry (e)-2-octenal, which smells fatty, green. The science ↓

Ingredients
Directions
Prepare the croutons
Cut stale bread into thin ½‑inch slices.
Stamp out shapes such as diamonds or rings.
Fry the shapes until golden brown.
Make the border and serve
To make a border, dip one side of each crouton in a mixture of egg white and flour.
Arrange the croutons around the edge of the dish.

Egg and flour barely smell alike, yet cooks put them together in 106,462 recipes: they work on texture and structure more than aroma.
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 crumb crisps and browns when fried, holding its shape well.
- White of 1 egg
- Its proteins set when heated, helping the coating bind to the crouton surface.
- Flour
- Thickens the egg white into a paste that clings to the crouton and helps it stick.
The step that matters
Dipping one side in the egg white and flour mixture. The coating should be thin and even. A thick or lumpy mixture clumps and may not adhere evenly, while too much liquid can make the croutons soggy and slow to set.
