Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Wild duck
- Provides the main meat, which becomes tender and browned through roasting.
- Breadcrumbs
- Absorb the seasoned juices inside the bird, adding moisture and body to the stuffing.
- Butter
- Adds fat for basting, helping the skin brown and the meat stay moist.
- Currant jelly
- Adds sweetness and body to the gravy, balancing the savory drippings.
- Brown flour
- Thickens the gravy as it cooks with the drippings, giving it body.
Swap the onion
The recipe marks onion as optional. How well each one fits the dish's main ingredients (carrot, pepper, sage, butter, currant, flour):
- Parsnipfits better
- Turnipfits better
- Capsicumfits better
- Onionthe original
Fit is the average pairing score against carrot, pepper, sage, butter, currant, flour. Candidates are from the same food group and used in at least 100 recipes.
