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 and place them in cold water immediately after cooking.
Once cold, carefully remove the shells and cut the eggs in half lengthwise.
Butter the cut sides of the eggs slightly.
Assemble and serve
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 for serving.

What each ingredient does
- Eggs
- Provide the main body of the sandwich, with firm whites that hold their shape when cut and pressed.
- Butter
- Adds a thin layer of fat and richness to the cut surfaces of the eggs.
- Sardines or pickled herring
- Supply a salty, savory filling that gives the sandwich its main flavor.
The step that matters
Pressing the halves together. Cut egg halves can slip or separate if the filling is uneven or the cut surfaces are too slick. Pressing firmly with the buttered sides meeting keeps the egg looking whole and the filling in place.
