Why it works: Celery and mustard are a kitchen classic. They rank in the top 2% of all ingredient pairs, and cooks put them together in 4,169 recipes. Both carry guaiacol, which smells smoky, sweet. The science ↓
Nut Salad
Ingredients
Directions
Make the mayonnaise
Combine chopped walnuts and celery in a bowl.
For the mayonnaise, whisk together egg yolk, salt, sugar, mustard, and cayenne pepper, then slowly add olive oil drop by drop while stirring continuously.
Moisten with lemon juice or vinegar to taste.
Make the salad dressing
For the salad dressing, hard boil the eggs, then separate the yolks.
Mash yolks with melted butter, salt, dry mustard, sugar, and pepper.
Gradually stir in milk or cream and enough vinegar to thicken.
Cook the mixture over low heat, stirring until smooth.
If using milk only, dissolve corn-starch in it to thicken.
Assemble and garnish
Garnish the salad with the whites of the hard-boiled eggs.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Walnuts
- Add crunch and a rich, nutty flavour to the salad.
- Egg yolk
- Emulsifies the oil into the mayonnaise, giving it a thick, smooth body.
- Olive oil
- Provides fat and richness, forming the body of the mayonnaise.
- Butter
- Adds richness and smooth mouthfeel to the dressing.
- Milk or cream
- Adds moisture and creaminess, thickening the dressing when heated.
- Corn-starch
- Thickens the milk-based dressing when heated.
The step that matters
Adding the olive oil. Oil must be added drop by drop while whisking, so it emulsifies into the yolk. Adding it too fast breaks the mixture, which then will not thicken into mayonnaise.
Swap the walnut
How well each one fits the dish's main ingredients (celery, egg, sugar, mustard, pepper, olive, lemon):
- Chickpeafits better
- Beansfits about as well

Fit is the average pairing score against celery, egg, sugar, mustard, pepper, olive, lemon. Candidates are from the same food group and used in at least 100 recipes.
