Why it works: Parsley and celery match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 6,810 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Chicken Sandwiches
Ingredients
Directions
Prepare the filling
Chop the cold cooked chicken very fine.
Add the finely chopped parsley and the yolk of a hard boiled egg.
Pound these ingredients to a paste.
Season with celery salt and onion juice, then moisten with salad dressing.
Assemble the sandwich
Spread the mixture on one slice of bread.
Place a lettuce leaf over the mixture, then top with the second slice of bread spread with butter or salad dressing.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold cooked chicken
- Forms the bulk of the filling and provides the main texture.
- Hard boiled egg yolk
- Adds richness and a creamy body that binds the paste together.
- Salad dressing
- Moistens the chicken mixture, adding fat and tang for a softer filling.
- Butter
- Coats the bread, adding fat and flavour and limiting moisture soaking in from the filling.
The step that matters
Pound the chicken, parsley and yolk to a paste. The chicken must be chopped very fine and pounded so the yolk and dressing blend evenly. Coarse pieces keep the filling dry and loose, so it will not spread or hold together in the sandwich.
Swap the lettuce
How well each one fits the dish's main ingredients (chicken, parsley, egg, celery, onion, bread, butter):
- Leekfits better
- Potatofits better
- Carrotfits better
- Lettucethe original
Fit is the average pairing score against chicken, parsley, egg, celery, onion, bread, butter. Candidates are from the same food group and used in at least 100 recipes.
