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 ↓
Scalloped Eggs
Ingredients
Directions
The book says “a hot oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 350°F (175°C).
In a bowl, mix the chopped eggs, grated onion, bread crumbs, salt, and pepper.
Transfer the mixture to a baking dish.
Bake
Pour enough milk over the mixture to cover it.
Dot the top with bits of butter.
Bake for 20 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Hard-boiled eggs
- Form the bulk of the dish and set into a soft, custardy texture as they bake.
- Bread crumbs
- Absorb the milk and help bind the mixture so it holds together when baked.
- Milk
- Moistens the mixture and cooks into a savory custard around the eggs.
- Butter
- Adds richness and helps the top brown as it bakes.
- Onion
- Adds savory aroma and a mild sharpness that flavors the custard.
