Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold boiled beef
- Provides the savoury, meaty flavour that forms the base of the dish.
- Cabbage
- Supplies the bulk of the dish and softens to a tender, mild texture when boiled and fried.
- Butter
- Adds fat for frying, giving richness and light browning to the greens and beef.
- Onion
- Adds sweetness and aroma as it cooks with the greens.
The step that matters
Frying the beef gently. Beef left over from boiling is already lean and has little moisture, so high heat or long cooking toughens and dries it. A gentle fry with a little butter warms it through while keeping it tender.
Swap the cabbage
