Why it works: Cabbage and pepper are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 4,081 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Duck and Red Cabbage
Ingredients
Directions
Prepare the cabbage
Wash and drain the cabbage.
Shred the cabbage finely.
Heat the butter in a stewpan.
Add the shredded cabbage to the stewpan. Season the cabbage with salt and pepper. Cover the stewpan closely.
Cook gently for 1 hour, adding gravy or stock as needed to prevent burning.
Cook the duck
Divide the ducks into neat joints.
Place the duck joints in a stewpan with just enough hot gravy or stock to barely cover them. Cover the stewpan with a close-fitting lid.
Cook just below simmering point for nearly 1 hour.
Serve
Add the vinegar to the cabbage.
Turn the cabbage onto a hot dish. Arrange the duck on top of the cabbage.
Serve with additional gravy, either poured around or served separately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Red cabbage
- Forms the bulk of the dish and becomes tender through slow, covered cooking.
- Butter
- Adds fat for richness and helps the shredded cabbage cook without sticking.
- Vinegar
- Adds acidity that brightens the flavour and helps the cabbage keep its colour.
- Cold ducks
- Provide the main meat, which is gently reheated in gravy until tender.
The step that matters
Keep the duck just below simmering. Gentle heat keeps the meat moist and tender. A rolling boil would toughen the muscle fibres and can dry or break up the joints.
Swap the cabbage
How well each one fits the dish's main ingredients (butter, vinegar, pepper):
- Capsicumfits better
- Mustardfits better
- Cabbagethe original
- Onionfits about as well
Fit is the average pairing score against butter, vinegar, pepper. Candidates are from the same food group and used in at least 100 recipes.
