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 sauce
Beat the egg yolk with flour, salt, sugar, and cayenne pepper.
Add boiling water and cook over steam, stirring constantly for 2 minutes.
Remove from heat and mix in cider vinegar, cream or milk, oil or melted butter, and onion juice.
Assemble and serve
In a bowl, combine 2 tablespoons of the sauce with the mashed potatoes and beat well.
Heap the potato mixture on a mound of cooked spinach.
Pour the remaining sauce over the salad. Serve hot or cold.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolk
- Emulsifies the sauce and thickens it as it cooks, giving a smooth, rich body.
- All-purpose flour
- Stabilizes the sauce with starch so it thickens without curdling during cooking.
- Cream or milk
- Adds moisture and richness, softening the sauce's tang.
- Oil or melted butter
- Adds fat for a smooth texture and mouthfeel in the dressing.
- Cider vinegar
- Adds acidity that brightens the sauce and balances its richness.
- Mashed potatoes
- Forms the bulk of the salad, adding body and a soft, starchy texture.
The step that matters
Cook the sauce over steam while stirring constantly. The egg yolk and flour must be heated gently while stirred. Egg proteins set and thicken the sauce, but if it overheats or stops moving, the yolk can scramble into lumps.
