Why it works: Walnut and lettuce 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 ↓
Apple Salad
Ingredients
Directions
Prepare the apples
Slice the top off each apple and scoop out the inside, being careful not to break the skin.
Make the filling
Chop the apple, celery, and nuts very finely in a chopping bowl.
Mix the chopped ingredients well with the mayonnaise.
Assemble and serve
Fill the apple shells with this mixture and replace the tops.
Through the stem holes, stick leafy stalks of celery.
Serve on lettuce leaves.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Red apples
- Hollowed shells that hold the filling and provide crisp, tart flesh.
- Celery
- Adds crunch and a fresh, watery texture to the filling.
- Nuts
- Add crunch and a toasty, slightly bitter flavor that contrasts the soft filling.
- Mayonnaise dressing
- Binds the chopped ingredients together and adds richness and moisture.
The step that matters
Scoop out the apples without breaking the skin. The skin forms the shell that holds the filling, so a torn skin lets the mixture leak out and weakens the presentation.
Swap the apple
How well each one fits the dish's main ingredients (celery, nuts, walnut, lettuce):
- Avocadofits better
- Limefits better
- Figfits better
- Applethe original
Fit is the average pairing score against celery, nuts, walnut, lettuce. Candidates are from the same food group and used in at least 100 recipes.
