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

What each ingredient does

Beef kidneys
Form the main body of the dish and brown on the outside when fried.
Onions
Add sweetness and savour as they soften and cook down in the pan.
Dry flour
Thickens the juices in the pan into a gravy.

The step that matters

Adding the flour to the onions and kidneys. Flour must be mixed evenly through the fat and juices before water is added; otherwise it clumps and leaves lumps in the gravy instead of thickening it smoothly.

Swap the onion

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

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

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