Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Add richness and a soft, creamy body to the salad.
- Potatoes
- Provide bulk and a tender, starchy base that holds the dressing.
- French dressing
- Adds moisture, fat and seasoning that coat the eggs and potatoes.
- Vinegar
- Adds acidity that sharpens the boiled dressing.
The step that matters
Dice the potatoes while hot. Warm potatoes are more porous and absorb dressing readily, so they take on flavour evenly. Once cold, they absorb less and the dressing sits on the surface.
Swap the potato
How well each one fits the dish's main ingredients (egg, watercress, vinegar):
- Horseradishfits better
- Shallotfits better
- Mustardfits better
- Potatothe original
Fit is the average pairing score against egg, watercress, vinegar. Candidates are from the same food group and used in at least 100 recipes.
