Why it works: Pepper and lemon match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Potato Salad
Ingredients
Directions
Prepare the salad
Combine the sliced potatoes, sliced eggs, diced ham, sweet pickle, salt, and pepper in a large bowl. Mix thoroughly.
Make the dressing
In a separate bowl, mix the salad sauce, raw egg yolks, cooked egg yolk, Worcestershire sauce, sugar, and pepper to prepare the dressing.
Slowly stir in the sweet oil, similar to making mayonnaise.
Add a few drops of lemon juice to the dressing.
Combine and garnish
Pour the dressing over the potato mixture, one spoonful at a time, mixing well after each addition.
Garnish with additional sliced eggs and pickles as desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the bulk of the salad and absorb the dressing, giving body to each bite.
- Raw egg yolks
- Emulsify the oil into the dressing, thickening it into a creamy, mayonnaise-like sauce.
- Sweet oil
- Provides fat and richness, forming the body of the emulsified dressing.
- Hard boiled eggs
- Add firm texture and richness to the salad.
- Potted ham
- Adds savory, meaty flavor and fat to the salad.
The step that matters
Adding the oil to the dressing. Oil must be added slowly while stirring so it emulsifies into the egg yolks; adding it too fast can break the dressing into separated oil and liquid.
Swap the potato
How well each one fits the dish's main ingredients (egg, ham, pepper, sauce, sugar, lemon):
- Capsicumfits better
- Mustardfits better
- Asparagusfits better
- Potatothe original
Fit is the average pairing score against egg, ham, pepper, sauce, sugar, lemon. Candidates are from the same food group and used in at least 100 recipes.
