Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold meat
- Provides the main body of the dish, browned in drippings for savory flavor.
- Remains of cold cabbage
- Forms the bulk of the vegetable mixture, softening and browning in the pan.
- Onion
- Adds sweetness and aroma as it softens and turns pale yellow in the fat.
- Drippings
- Supplies fat for frying, adding richness and helping the meat and vegetables brown.
The step that matters
Fry the vegetables until slightly brown. Browning relies on surface heat and enough fat; if the vegetables are crowded or steamed, they stay pale and soft instead of developing toasty, savory flavor through the Maillard reaction.
Swap the onion
How well each one fits the dish's main ingredients (meat, cabbage, pepper):
- Mustardfits better
- Capsicumfits better
- Cauliflowerfits better
- Onionthe original
Fit is the average pairing score against meat, cabbage, pepper. Candidates are from the same food group and used in at least 100 recipes.
