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 ↓
English Walnut Salad
Ingredients
Directions
Prepare the walnuts
Boil the walnut meats with the onion slice, bay leaf, and coarse sea salt until slightly softened.
Drain and cool.
Make the dressing
In a bowl, combine the coarse sea salt and white pepper.
Add the salad oil and onion juice, rubbing until the salt dissolves.
Mix in the additional salad oil and vinegar, beating until the mixture is whitish and thick.
Serve
Serve the salad on a bed of lettuce and garnish with orange slices cut into points.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- English walnut meats
- Form the main body of the salad and provide a rich, nutty flavor and crisp-tender bite after boiling.
- Salad oil
- Carries fat-soluble flavors and gives the dressing a smooth, rich body.
- Vinegar
- Adds acidity that brightens the dressing and balances the richness of the oil.
- Coarse sea salt
- Seasons the walnuts and, rubbed with the oil, helps dissolve into the dressing.
The step that matters
Beating the dressing until whitish and thick. Beating whisks air into the oil and vinegar mixture and helps it emulsify, so it turns pale and thick instead of separating into layers. Stopping too early leaves a thin, oily dressing that will pool on the lettuce.
Swap the white pepper
How well each one fits the dish's main ingredients (walnut, meat, onion, vinegar, lettuce, orange):
- Tarragonfits better
- Thymefits better
- Celeryfits better
- White pepperthe original
Fit is the average pairing score against walnut, meat, onion, vinegar, lettuce, orange. Candidates are from the same food group and used in at least 100 recipes.
