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 vegetables
Rub the boiled potatoes through a colander, then let the potatoes cool.
Shred the cabbage and celery finely with a sharp knife.
Rub the yolks of two hard-boiled eggs to a powder.
Toss the powdered yolks with the potatoes, cabbage, and celery using a silver fork.
Make the dressing
Beat the two egg yolks, melted butter, sugar, corn-starch, salt, mustard, cayenne, and vinegar until smooth.
Heat the vinegar mixture.
Pour the heated mixture over the potato mixture, stirring constantly until it thickens, about two minutes.
Whip the mixture into the potato salad.
Chill
Set the salad aside until very cold.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Boiled potatoes
- Mealy potatoes form the bulk of the salad and break down softly for a creamy body.
- Egg yolks
- Egg yolks thicken the dressing as they heat and add richness to the salad.
- Melted butter
- Butter adds fat, giving the dressing a smooth, rich mouthfeel.
- Vinegar
- Vinegar adds acidity that balances the richness of the yolks and butter.
- Corn-starch
- Corn-starch thickens the heated dressing so it clings to the potatoes.
- White cabbage
- Shredded cabbage adds crisp texture and a mild bite to the salad.
The step that matters
Pour the heated dressing and stir constantly. Egg yolks and corn-starch thicken as they heat. Stirring constantly keeps the mixture smooth and prevents the yolks from curdling in lumps while it thickens.
Swap the cabbage
How well each one fits the dish's main ingredients (potato, celery, egg, butter, sugar, corn, mustard):
- Chivefits better
