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, which browns in the roux and becomes tender through slow stewing.
Butter: Forms the roux with browning flavour and fries the turnips to golden brown.
Broth: Forms the liquid base of the gravy that the duck stews in.
Turnips: Add sweet, earthy flavour and body, and are mashed to make the side dish.
Cream: Adds richness and smoothness to the turnip mash.
Arrowroot or flour: Thickens the gravy so it coats the duck.

The step that matters

Adding the turnips at three-quarters cooked. Turnips cook faster than duck, so adding them too early can leave the duck undercooked or turn the turnips mushy. Timing them late lets both finish together with the right texture.
