Roast Wild Duck

Oven, in the book's wordsA hot oven

Ingredients

Directions

The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Prepare the duck

  1. Do not dress the wild duck too soon after killing.

  2. Keep the duck for several days in cold weather.

  3. Optionally, parboil the duck with a peeled carrot or onion to reduce fishy flavor before roasting.

Roast

  1. Preheat the oven to 400°F (200°C).

  2. Bake the duck for 5-10 minutes without basting to retain gravy.

  3. Baste frequently with butter and water for 30-40 minutes until cooked.

Make the sauce and serve

  1. Mix Worcestershire sauce, mushroom ketchup, salt, cayenne pepper, and lemon juice in a small saucepan.

  2. Heat the sauce.

  3. Stir in prepared mustard.

  4. Pour the sauce into a hot gravy boat.

  5. Serve the duck on a hot dish with a cut lemon.

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 is cooked through by roasting and basting.
Butter
Adds fat and richness to the basting, helping the skin brown and the meat stay moist.
Worcestershire sauce
Contributes savory, tangy depth to the sauce.
Mushroom ketchup
Adds savory umami flavor to the sauce.
Lemon juice
Adds acidity that brightens the rich, gamey sauce.

The step that matters

Parboiling the duck with carrot or onion. Parboiling is optional and aims to reduce the fishy flavor of wild duck. Wild ducks often have a stronger, gamier taste than farmed birds, so this step can noticeably improve the result. Skipping it is a matter of taste rather than safety.

Swap the carrot

The recipe marks carrot as optional. How well each one fits the dish's main ingredients (butter, sauce, mushroom, ketchup, pepper, lemon, mustard):

  1. Shallotfits better
  2. Horseradishfits better
  3. Capsicumfits better
  4. Carrotthe original

Fit is the average pairing score against butter, sauce, mushroom, ketchup, pepper, lemon, mustard. Candidates are from the same food group and used in at least 100 recipes.
