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 Ham and Eggs
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Chop the egg whites finely and press the yolks through a vegetable press.
Assemble
In buttered scallop shells, layer chopped ham, then chopped egg whites.
Pour some cream sauce over the layers.
Add another layer of ham and a layer of sifted yolks.
Cover with more cream sauce and sprinkle with moistened bread crumbs.
Bake
Bake in a 400°F (200°C) oven until golden brown.

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 of the dish, with whites chopped and yolks pressed to a fine texture.
- Cream sauce
- Adds moisture and richness so the layers stay creamy rather than dry while baking.
- Boiled ham
- Contributes savory, salty flavor and chewy texture between the egg layers.
- Bread crumbs
- Form a crisp, golden topping that browns in the oven.
- Butter
- Adds fat that helps the crumb topping brown and gives a rich flavor.
The step that matters
Bake until golden brown. The topping needs enough heat to brown without drying the cream sauce underneath. Watching colour lets you stop before the sauce splits or the eggs toughen.
