Directions
Prepare
Prepare the duck by cleaning and washing it well.
Slice the heart of the cabbage into fine long strips, then wash and drain the cabbage.

Stuff the duck with the cabbage mixture.
Bake or roast the duck until fully cooked.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Duck
- Provides the main protein and rich fat that bastes the meat as it roasts.
- Cabbage
- Adds moisture and a mild, tender filling that steams inside the bird.
- Butter
- Adds fat that carries flavor and promotes browning on the outside of the duck.
- Garlic
- Contributes aroma and savory pungency that mellows during roasting.
The step that matters
Roast until fully cooked. Duck is dense and fatty, and the stuffing slows heat reaching the center. Cooking until fully done ensures the meat is safe to eat, and the cabbage filling must reach the same temperature.
Swap the onion
The recipe marks onion as optional. How well each one fits the dish's main ingredients (cabbage, pepper, clove, garlic, butter, potato, mint):
- Chivefits better
- Broccolifits about as well
- Spinachfits about as well
- Onionthe original
Fit is the average pairing score against cabbage, pepper, clove, garlic, butter, potato, mint. Candidates are from the same food group and used in at least 100 recipes.
