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 ↓
Potato Salad
Ingredients
Directions
Prepare the dressing
For the dressing, beat 4 eggs lightly in a double boiler.
Add sugar, salt, red pepper, mustard, sweet cream, and vinegar to the eggs.
Cook the mixture in the double boiler until it thickens.
Layer the salad
Slice fresh boiled potatoes into small bits while still warm.
Layer potatoes in a dish, sprinkle with celery, salt, and pepper.
Add a layer of sliced hard-boiled eggs and a little more salt and pepper.
If desired, add diced cold boiled beet for color.
Drizzle a liberal amount of dressing over each layer and continue until the dish is filled.
Chill
Allow the salad to stand in a cool place for 24 hours before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Cooked into the dressing, where they thicken it to a creamy consistency.
- Sweet cream
- Adds richness and body to the dressing, softening its sharpness.
- Vinegar
- Adds acidity that balances the sweetness and richness of the dressing.
- Sugar
- Balances the acidity of the vinegar and mustard in the dressing.
- Potatoes
- Form the bulk of the salad and soak up the dressing as it stands.
The step that matters
Cooking the dressing until it thickens. Eggs thicken when heated gently; if the heat is too high or the mixture is left too long, the eggs can scramble and curdle. A double boiler keeps the heat gentle and even.
Swap the potato
How well each one fits the dish's main ingredients (celery, pepper, egg, sugar, mustard, cream, vinegar):
- Horseradishfits better
- Capsicumfits better
- Lettucefits better
- Potatothe original
Fit is the average pairing score against celery, pepper, egg, sugar, mustard, cream, vinegar. Candidates are from the same food group and used in at least 100 recipes.
