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 Cucumber Salad
Ingredients
Directions
Assemble the salad
In a dish, layer the sliced potatoes, cucumbers, celery, eggs, and a sprinkle of grated onion until all ingredients are used.
Make the dressing
For the dressing, beat the eggs well and mix in melted butter, sugar, salt, and mustard until smooth.
Add vinegar and cook in a double boiler, stirring until smooth.
Once cooled, fold in the beaten cream.
Serve
Before serving, pour the dressing over the salad.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Beaten eggs thicken the dressing as they cook, giving it a creamy body.
- Vinegar
- Adds acidity that sharpens the dressing and balances the sugar and richness.
- Cream
- Adds richness and a smooth, creamy texture to the finished dressing.
- Potatoes
- Form the bulk of the salad, providing starchy body that soaks up the dressing.
- Butter
- Adds fat and richness to the dressing.
The step that matters
Cooking the dressing in a double boiler. Eggs can scramble if heated too quickly. Gentle indirect heat, with constant stirring, lets the egg proteins thicken the vinegar mixture smoothly.
