Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Cold boiled potatoes
Provide the main bulk; their starch crisps and browns when fried in fat.
Dripping or butter
Conducts heat for frying and adds richness and flavour to the potatoes.
Finely minced onion
Softens and browns in the fat, adding sweetness and savoury aroma.

The step that matters

Fry until light brown. Frying the onion until light brown develops sweetness and flavour in the fat before the potatoes go in. Stopping too early leaves a raw, sharp taste, while going too far can scorch the onion and make the dish bitter.

Swap the onion

How well each one fits the dish's main ingredients (potato, butter, pepper, parsley):

  1. Carrotfits better
  2. Chivefits better
  3. Capsicumfits better
  4. Onionthe original

Fit is the average pairing score against potato, butter, pepper, parsley. Candidates are from the same food group and used in at least 100 recipes.
