Why it works: Egg and butter are a kitchen classic. They rank in the top 17% of all ingredient pairs, and cooks put them together in 118,967 recipes. Both carry decanal, which smells soap, orange peel. The science ↓
Egg Sandwiches
Ingredients
Directions
Prepare the eggs
Boil the eggs hard.
Transfer the boiled eggs to cold water.
Once cold, carefully remove the shells and cut the eggs in half lengthwise.
Butter the cut sides slightly.
Assemble and decorate
Place one or two sardines on one half of the egg and press the other half on top to make the egg appear whole.
Tie the eggs with colored ribbons lengthwise and across, finishing with a bow.
Arrange the decorated eggs in a fancy basket.

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.

Shared aroma: decanal (soap, orange peel).

What each ingredient does
- Eggs
- Provide the main structure and body of the sandwich filling, shaped into halves.
- Butter
- Adds a thin layer of fat to the cut eggs for richness and a smoother mouthfeel.
- Sardines or pickled herring
- Supply the salty, savory filling hidden inside the egg halves.
The step that matters
Carefully remove the shells after cooling. Eggs cooled in cold water contract slightly and separate from the shell, which helps keep the whites intact. Rough handling can tear the delicate white, leaving the halves ragged and harder to press back together neatly.
