Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pork
- Provides the meat, which becomes tender and absorbs flavour as it simmers in the gravy.
- Onions
- Soften and turn sweet as they fry, adding depth and aroma to the sauce.
- Butter
- Fat for frying that carries flavour and helps the pork and onions brown.
- Flour
- Thickens the gravy so it coats the cutlets rather than running thin.
- Gravy
- Supplies the main liquid and savoury body, keeping the meat moist as it simmers.
- Vinegar
- Adds a small amount of acidity that sharpens and brightens the rich sauce.
The step that matters
Fry until light brown. Browning the cutlets and onions builds savoury flavour through the Maillard reaction. Pale frying leaves the sauce flat, while over-browning turns it bitter.
Swap the onion
How well each one fits the dish's main ingredients (pork, butter, flour, pepper, vinegar, mustard):
- Shallotfits better
- Lettucefits 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.
