Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pork loin
- Provides the main meat, which is already cooked and is simply reheated in the sauce.
- Butter
- Carries the frying heat and adds richness and browning to the onions and cutlets.
- Onions
- Soften and turn sweet as they fry, adding savoury depth to the sauce.
- Flour
- Thickens the gravy into a smooth sauce that clings to the cutlets.
- Gravy
- Supplies the liquid base and savoury flavour of the sauce.
- Mustard
- Adds a sharp, tangy bite that balances the richness of the pork and butter.
The step that matters
Frying until light brown. Browning the cutlets and onions in butter develops savoury, roasted flavours through the Maillard reaction. Pale frying gives a flatter taste, while over-browning can taste bitter.
Swap the onion
How well each one fits the dish's main ingredients (pork, butter, flour, pepper, vinegar, mustard):
- Shallotfits better

- Capsicumfits better
- Onionthe original
Fit is the average pairing score against pork, butter, flour, pepper, vinegar, mustard. Candidates are from the same food group and used in at least 100 recipes.
