Directions
Prepare and stew
Coat the duck pieces well with flour.
Place them in a stewpan with mushroom ketchup, Harvey sauce, port wine, and a little water or stock.

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 during slow simmering.
- Flour
- Coats the duck and helps thicken the sauce as it cooks.
- Port wine
- Adds sweetness and depth to the sauce as it reduces.
- Mushroom ketchup
- Adds savoury, umami depth to the sauce.
The step that matters
Simmer without boiling. Gentle simmering keeps the duck tender and the sauce smooth. A hard boil toughens meat proteins and can break the sauce, so keep the heat low and steady.
