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 stew, becoming tender as they stew gently.
- Flour
- Thickens the cooking liquid into a light gravy around the kidney slices.
The step that matters
Frying the kidney slices until light brown. Searing the surface builds browned flavour through the Maillard reaction and helps the slices hold their shape. Pale, underbrowned slices give a flatter taste in the finished stew.
Swap the parsley
The recipe marks parsley as optional. How well each one fits the dish's main ingredients (beef, pepper, flour):
- Turmericfits better
- Jalapenofits about as well
- Marjoramfits about as well
- Parsleythe 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.
