Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Minced meat
- Forms the main body of the dish and provides savoury meaty flavour as it browns.
- Flour
- Thickens the cooking liquid into a light gravy as it simmers with the water.
- Onion
- Adds sweetness and aroma as it softens in the pan.
The step that matters
Stirring the meat until each piece is separate. If the mince is left in clumps, it steams unevenly and stays grey and lumpy. Stirring as it cooks breaks it up so the pieces brown and cook evenly.
Swap the onion
How well each one fits the dish's main ingredients (meat, flour, mushroom, ketchup):
- Shallotfits better
- Capsicumfits better
- Arrowrootfits better
- Onionthe original
Fit is the average pairing score against meat, flour, mushroom, ketchup. Candidates are from the same food group and used in at least 100 recipes.
