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

What each ingredient does

Dripping or butter
Adds fat for frying and a rich, savory flavor to the onion and potatoes.
Onion
Becomes sweet and aromatic as it cooks slowly until pale yellow.
Cold boiled potatoes
Provide the bulk and soft, tender texture of the filling, and brown lightly in the fat.

The step that matters

Cooking the potatoes until slightly colored. Stirring frequently spreads heat so the potatoes brown lightly without scorching. Light browning adds savory, toasted flavor through the Maillard reaction, while burning leaves a bitter taste.

Swap the onion

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

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

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