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 ↓
Chicken Sandwiches
Ingredients
Directions
Prepare the filling
Mince the cold roast or boiled chicken in a chopping bowl.
Mix in the gravy and add the minced hard-boiled eggs.
Season with salt and pepper as needed to create a soft paste.
Assemble and serve
Cut slices of bread and butter them.
Spread the chicken mixture between the slices and press gently together.
Arrange the sandwiches on a fringed napkin on a serving tray.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chicken
- Forms the bulk of the filling, giving it savory meat flavor and body.
- Gravy
- Adds moisture and flavor, helping bind the chicken into a soft paste.
- Hard-boiled eggs
- Add richness and a soft, creamy texture to the filling.
- Butter
- Adds fat and flavor to the bread and helps keep it from soaking up moisture from the filling.
The step that matters
Seasoning the chicken paste. Salt needs to be distributed evenly through the minced chicken, eggs and gravy. Too little leaves the filling bland, while too much makes it harsh, and the paste should stay soft enough to spread.
Swap the mustard
The recipe marks mustard as optional. How well each one fits the dish's main ingredients (chicken, egg, pepper, bread, butter):
- Capsicumfits better
- Asparagusfits better
- Potatofits better
- Mustardthe original
Fit is the average pairing score against chicken, egg, pepper, bread, butter. Candidates are from the same food group and used in at least 100 recipes.
