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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Olives
- Provide the main savory filling and briny flavour.
- Mayonnaise
- Binds the chopped filling together and keeps it moist.
- Celery
- Adds crisp texture to the soft olive filling.
- Graham bread
- Forms the thin slices that hold the filling.
- Butter
- Adds fat and richness and helps keep the bread from soaking up moisture.
The step that matters
Chopping the filling finely and evenly. Uniform small pieces spread into a thin, even layer and bind well with mayonnaise, so each bite has balanced texture and the bread does not tear under coarse chunks.
Swap the onion
How well each one fits the dish's main ingredients (olive, parsley, celery, mustard, bread, butter):
- Lettucefits better
