Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Duck
- Provides the main meat, whose fat renders during roasting to keep the flesh moist and crisp the skin.
- Sage and onion forcemeat
- Adds savoury, aromatic flavour and moisture to the cavity while the bird roasts.
- Port wine
- Adds sweetness and depth to the gravy when used.
The step that matters
Roasting time for the duck. Duck size varies, so the bird can easily be under- or overcooked. Duck is safe and juicy at the correct internal temperature, and checking it near the end of the time range helps avoid dry meat.
Swap the sage
How well each one fits the dish's main ingredients (onion, port wine):
- Garlicfits better
- Thymefits better
- Clovefits better
- Sagethe original
Fit is the average pairing score against onion, port wine. Candidates are from the same food group and used in at least 100 recipes.
