Why it works: Lettuce and walnut match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 491 recipes. Both carry trans-2-hexenal, which smells green, leafy. The science ↓
Walnut Salad
Ingredients
Directions
Assemble the nested salad
Make a nest of lettuce leaves on a salad dish.
Cut the orange into slices and then the slices into quarters.
Arrange the orange quarters on the lettuce.
Add a few halves of English walnuts on top.
Place a thin layer of mayonnaise dressing on each piece. Serve.
Make the chopped salad
Chop the lettuce and the whites of the hard-boiled eggs separately, not too fine.
Toss the lettuce and egg whites lightly together.
Sprinkle the top thickly with English walnuts and coarsely chopped egg yolks.
Pour over any good salad dressing.
Serve on crisp lettuces.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lettuce
- Provides a crisp, fresh base that holds the other ingredients.
- Orange
- Adds juiciness, sweetness and acidity that brighten the salad.
- English walnuts
- Add crunch and a rich, fatty flavour against the softer ingredients.
- Mayonnaise dressing
- Adds fat and creaminess, coating each piece with moisture and richness.
- Hard-boiled eggs
- Yolks add richness and body, while the whites contribute a firm, mild texture.
The step that matters
Chop the lettuce and egg whites separately, not too fine. Chopping too finely bruises the lettuce and breaks down the egg whites, releasing water and turning the salad soft and watery instead of crisp with distinct pieces.
Swap the orange
How well each one fits the dish's main ingredients (lettuce, walnut, egg):
- Avocadofits better
- Figfits better
- Cherryfits better
- Orangethe original
Fit is the average pairing score against lettuce, walnut, egg. Candidates are from the same food group and used in at least 100 recipes.
