Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Make up the bulk of the salad and hold their shape when cut and gently mixed.
- Oil
- Carries flavor and adds richness and a smooth mouthfeel to the dressing.
- Vinegar
- Adds acidity that brightens the dressing and balances the richness of the oil.
- Onion
- Adds sharp aroma and pungency that softens as the salad rests.
The step that matters
Lightly mix the ingredients. Cold potatoes are firm, and vigorous stirring breaks their cell walls and releases starch, which turns the salad mushy and gummy. Gentle folding keeps the pieces intact while the dressing coats them.
Swap the potato
How well each one fits the dish's main ingredients (onion, vinegar, pepper):
- Capsicumfits better
- Mustardfits better
- Cabbagefits better
- Potatothe original
Fit is the average pairing score against onion, vinegar, pepper. Candidates are from the same food group and used in at least 100 recipes.
