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
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Cut stale bread into 1½ inch thick slices.
Scoop out the middle, leaving ½ inch thick sides and bottom.
Toast the bread rounds.
Bake
Place a raw egg in the center of each round.
Bake in the oven at 350°F (175°C) until the egg is set.

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.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Stale bread
- Forms the edible cup that holds the egg, and its drier crumb keeps its shape when hollowed and toasted.
- Raw eggs
- Set when heated, with their proteins coagulating to form a firm, sliceable filling inside the bread.
The step that matters
Bake until the egg is set. Egg proteins coagulate as they heat, so the white turns opaque and firm while the yolk stays runny if it is only just set. Underbaking leaves the white liquid, while overbaking makes the yolk chalky and rubbery.
