Why it works: Olive and lettuce match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and 2,580 recipes mention both. Both carry trans-2-hexenal, which smells green, leafy. The science ↓
Egg Salad
Ingredients
Directions
Prepare
Cut the hard-cooked eggs in half and remove the yolks.
Make the filling
Mix the yolks with the chopped olives and mayonnaise dressing.
Fill the egg whites with the yolk mixture, rounding the top to resemble a whole yolk.
Serve
Serve on a bed of lettuce or watercress.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Hard-cooked eggs
- Provide the whites that hold the filling and the yolks that form it.
- Olives
- Add salty, briny flavor and a bit of texture to the yolk filling.
- Mayonnaise dressing
- Binds the mashed yolks into a smooth, spreadable filling and adds moisture and richness.
The step that matters
Rounding the yolk filling in the whites. Mounding the filling gives a convincing whole-yolk look. Packing it too loosely or too wet can make it slump or leak, so the filling should be firm enough to hold its shape.
Flavor stand-ins for the lettuce
How well each one fits the dish's main ingredients (egg, olive):

- Tomatobetter flavor fit
- 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. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
