Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Boiled beef
- Provides the main protein and savory flavor, warmed through in the gravy.
- Cabbage
- Forms the bulk of the dish and adds a slightly sweet, earthy flavor when fried.
- Onion
- Softens as it fries, adding sweetness and depth to the base.
- Gravy
- Adds moisture and rich savoury flavor that binds the beef and onion.
- Dripping
- Fat for frying that browns the beef and cabbage and carries flavor.
The step that matters
Frying the cabbage until hot and lightly browned. Cabbage that is not dried and fried properly stays wet and steams, so it lacks browning and flavor. Keeping the fat hot lets surface moisture evaporate and caramelize some sugars.
