Why it works: Olive and lettuce match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 2,580 recipes. Both carry trans-2-hexenal, which smells green, leafy. The science ↓
Olive and Egg Salad
Ingredients
Directions
Prepare the eggs
Remove shells from the hard boiled eggs.
Cut the egg whites into fifths lengthwise, removing the yolks.
Curl the egg white petals and tint them with beet juice.
Make and assemble
Mash the yolks into a soft cream and mix in the chopped olives and paprika.
Mold the yolk mixture into balls and return them to the curled egg white petals.
Prick the surface with a fork to roughen it.
Top each with a tablespoon of mayonnaise and set in a nest of crisp lettuce.

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, with whites forming the petals and yolks forming the filling.
- Olives
- Add salty, briny flavor and a contrasting texture to the mashed yolk filling.
- Mayonnaise
- Adds fat and moisture, giving the yolk mixture a soft, creamy texture.
The step that matters
Mash the yolks into a soft cream. Yolks must be mashed fully smooth before the olives are added; lumps of yolk hold together poorly and make the balls crumble when molded. Mixing evenly also spreads the paprika through the filling.
Swap the lettuce
How well each one fits the dish's main ingredients (egg, olive):
- Capsicumfits better
- Asparagusfits better
- Tomatofits better
- Lettucethe original
Fit is the average pairing score against egg, olive. Candidates are from the same food group and used in at least 100 recipes.
