Why it works: Butter and bread 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 ↓
Egg Sandwiches
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 400°F (200°C).
Soften a little butter in a narrow cake tin.
Bake the eggs
Break in 12 fresh eggs, adding salt and pepper to taste.
Place small pieces of butter over the top, being careful not to break the yolks.
Bake for 20 minutes, then set aside to cool.
Assemble
Turn out the baked eggs and cut into slices.
Place the egg slices between thin slices of buttered bread.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set to a firm, sliceable body when baked, holding the sandwich together.
- Butter
- Adds richness and moisture, and helps the eggs release from the tin and brown lightly.
- Buttered bread
- Provides a soft, contrasting base and carries the baked egg slices.
The step that matters
Place butter without breaking the yolks. Egg proteins set as they heat, so a broken yolk spreads and changes the texture of the baked eggs. Keeping yolks intact gives clean slices.
