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 gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Chop the hard-boiled eggs into small pieces.
Assemble and bake
In a baking dish, layer the chopped eggs, bread crumbs, butter, and salt alternately, making sure to have bread crumbs on top.
Pour the milk over the entire dish.
Bake in a 350°F (175°C) oven until brown.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Hard-boiled eggs
- Provide the main body and rich, firm texture of the dish.
- Bread crumbs
- Add structure and absorb milk, forming a soft layer that browns on top.
- Butter
- Adds richness and helps the top crumbs brown during baking.
- Milk
- Moistens the layers and bakes into a creamy, set custard around the eggs.
The step that matters
Pour the milk over the entire dish. The milk must soak down through all the layers so the crumbs and eggs are evenly moist. Dry spots will stay bland and may not set into a cohesive, creamy bake.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
