Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef collops
- Provide the main meat, which browns and forms the body of the dish.
- Bread crumbs
- Absorb liquid and thicken the mixture slightly as it cooks.
- Butter
- Adds fat for cooking the onion and carries flavour through the dish.
- Onion
- Softens and adds sweetness and aroma to the base.
The step that matters
Browning the beef collops. Beef left crowded or wet in the pan steams instead of browning. Browning builds savoury flavour through the Maillard reaction, so cook in a single layer over sufficient heat and let the meat brown before stirring.
Swap the onion
How well each one fits the dish's main ingredients (beef, pepper, butter, ketchup, bread):
- Capsicumfits better
- Tomatofits about as well
- Onionthe original
- Carrotfits about as well
Fit is the average pairing score against beef, pepper, butter, ketchup, bread. Candidates are from the same food group and used in at least 100 recipes.
