Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Duck
- Provides the meat that becomes tender during slow stewing and flavors the liquid.
- Butter
- Adds fat that enriches the stewing liquid and carries flavor.
- Onion
- Softens as it stews, adding sweetness and aroma to the sauce.
- Peas
- Add sweetness and a tender texture to the finished sauce.
- Parsley
- Contributes a fresh, herbal aroma to the stew.
- Mint
- Adds a bright, aromatic note that lifts the rich duck sauce.
The step that matters
Let it stew until nearly done. Slow, gentle simmering breaks down the connective tissue in duck so the meat becomes tender. Stewing too hard can toughen the meat and reduce the sauce too quickly, so the timing and heat need watching.
Swap the onion
How well each one fits the dish's main ingredients (butter, parsley, mint, pepper, peas):
