Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef kidney
- Provides the main protein and meaty texture of the stew.
- Flour
- Thickens the pan liquid into a light gravy as it cooks.
The step that matters
Frying the kidney slices until light brown. Searing the surface over high heat browns the proteins and builds savory flavor. Overcooking or crowding the pan makes the slices tough and steams them grey instead of browning.
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.
