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 dish and brown on their cut faces in the hot butter.
Butter
Carries heat evenly through the pan and adds richness and browning.
Onion
Softens and turns sweet and aromatic as it cooks in the butter.

The step that matters

Cook for 15 minutes, stirring occasionally. Leaving the potatoes mostly undisturbed lets their cut sides contact the hot pan and brown, which gives flavour and crispness. Stirring too often prevents this and can break the potatoes apart, so stir gently and only now and then.

Swap the onion

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

  1. Capsicumfits about as well
  2. Chivefits about as well
  3. Onionthe original
  4. Carrotfits about as well

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