Name: Waldorf Salad
Ingredients: 1 cup tart apple, diced; 1 cup celery, chopped; ⅓ cup English walnuts, coarsely chopped; mayonnaise dressing; lettuce leaves; whipped cream (optional)

Why it works: Walnut and lettuce match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and 491 recipes mention both. Both carry trans-2-hexenal, which smells green, leafy. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Tart apple: Provides crisp texture and a sharp, acidic contrast to the dressing.
Celery: Adds crunch and a fresh, mild vegetal flavor.
English walnuts: Add crunch and a mildly bitter, toasty note against the sweet dressing.
Mayonnaise dressing: Binds the ingredients together and adds fat and creaminess for moisture.
