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
Rub the boiled potatoes through a colander and let them cool.
Shred the cabbage and celery finely with a sharp knife.
In a bowl, toss the potatoes, cabbage, celery, and powdered egg yolks together with a silver fork.
Make the dressing
In a separate bowl, mix the beaten egg yolks, melted butter, sugar, corn-starch, salt, mustard, cayenne, and vinegar.
Heat the vinegar mixture and pour it over the potato mixture, stirring well.
Cook the mixture for 2 minutes while stirring constantly until it thickens.
Finish
Whip the mixture into the potato salad and set aside until very cold.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Beaten yolks thicken the dressing as they cook and add richness to the salad.
- Boiled potatoes
- Mealy potatoes form the body of the salad and soak up the dressing.
- Butter
- Melted butter adds fat, smoothness and richness to the dressing.
- Corn-starch
- Starch swells with heat and helps the dressing thicken.
- Vinegar
- Vinegar adds acidity that sharpens the flavour and balances the sweetness.
- Sugar
- Sugar adds sweetness that balances the sharp vinegar.
The step that matters
Cooking the dressing until it thickens. Egg yolks and starch thicken only with gentle, constant stirring over heat. If the mixture is left unstirred or runs too hot, the yolks can scramble into lumps and the dressing will not stay smooth.
Swap the cabbage
How well each one fits the dish's main ingredients (potato, celery, egg, butter, sugar, corn, mustard):
- Chivefits better
- Asparagusfits better
- Capsicumfits better
- Cabbagethe original
Fit is the average pairing score against potato, celery, egg, butter, sugar, corn, mustard. Candidates are from the same food group and used in at least 100 recipes.
