Why it works: Cider and vinegar are a kitchen classic. They rank in the top 6% of all ingredient pairs, and cooks put them together in 3,431 recipes. Both carry 4-ethyl-2-methoxyphenol, which smells smoky, clove. The science ↓
Potato Salad
Ingredients
Directions
Make the dressing
Combine cider vinegar, coarse sea salt, and granulated sugar in a saucepan.
Heat the mixture until boiling.
Mix flour, mustard, and butter with a little water to a smooth paste in a bowl.
Stir the paste into the boiling vinegar mixture and remove from heat.
Beat the egg and stir it into the mixture after removing from heat.
Allow the mixture to cool.
Thin the dressing with cream or milk as desired.
Assemble the salad
Boil the potatoes until tender, then let them cool and cut into dice.
Add diced potatoes, celery, and onion to the dressing. Season with white pepper.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the dressing into a smooth, creamy coating as it cooks.
- Egg
- Adds richness and body to the dressing as it thickens with the vinegar mixture.
- Cider vinegar
- Provides the acidity that gives the dressing its sharp, tangy flavour.
- Granulated sugar
- Balances the sharpness of the vinegar with sweetness.
- Butter
- Adds fat and a rich mouthfeel to the dressing.
- Potatoes
- Form the bulk of the salad and soak up the dressing's flavour.
The step that matters
Stirring the egg into the hot mixture. Egg proteins can scramble if the mixture is too hot or the egg is added too quickly. Removing the pan from heat first and stirring steadily keeps the dressing smooth and thickened.
Swap the mustard
How well each one fits the dish's main ingredients (cider, vinegar, sugar, flour, butter, egg, cream):
- Mustardthe original
- Shallotfits about as well
- Cucumberfits about as well
- Horseradishfits about as well
Fit is the average pairing score against cider, vinegar, sugar, flour, butter, egg, cream. Candidates are from the same food group and used in at least 100 recipes.
