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 ↓
Piquant Sandwiches
Ingredients
Directions
Prepare the filling
In a bowl, mix the minced hard-boiled eggs with the chopped green pickle.
Season the mixture with salt and pepper, then work in a little butter.
Assemble the sandwiches
Cut the bread into very thin slices and lightly butter one side of each slice.
Spread the filling on the unbuttered side of a slice of bread.
Top with another slice of bread, buttered side down, and cut into squares or triangles.

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 filling, setting into a soft, spreadable texture.
- Sharp green pickle
- Adds acidity and sharp flavour that cuts through the richness of the eggs and butter.
- Butter
- Adds fat and richness, carrying flavour and keeping the filling moist and smooth.
- Bread
- Forms the thin structure that holds the filling and gives the sandwich its body.
The step that matters
Work in the butter with the seasoned filling. Mixing the butter in while the egg and pickle are still well combined helps the filling become smooth and spreadable rather than dry or crumbly, and seasoning first lets the salt distribute evenly through the mixture.
