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

  1. Do not dress the wild duck too soon after killing; keep it for several days in cold weather.

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

Roast the duck

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

  2. Baste frequently with butter and water for 30 to 40 minutes until cooked.

  3. Serve on a very hot dish with a cut lemon.

Make the sauce

  1. For the sauce, combine Worcestershire sauce, mushroom ketchup, salt, cayenne pepper, and lemon juice in a small saucepan. Heat the mixture, then remove from heat and stir in prepared mustard.

  2. Pour the sauce into a hot gravy boat.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Wild duck
Is the main protein; its fat and meat become the dish.
Butter
Adds fat and richness, and helps browning and flavour as the duck roasts.
Worcestershire sauce
Adds savoury, tangy depth to the sauce.
Mushroom ketchup
Adds concentrated savoury, umami flavour to the sauce.
Lemon juice
Adds acidity that brightens the rich duck and sauce.

The step that matters

Bake without basting at first. Basting in the first minutes cools the surface and interrupts browning. Letting the skin dry and heat undisturbed helps it crisp, and later basting keeps the meat moist as it cooks.

Swap the lemon

How well each one fits the dish's main ingredients (butter, sauce, mushroom, ketchup, pepper, mustard):

  1. Lemonthe original
  2. Limefits about as well
  3. Avocadofits about as well
  4. Red currantfits less well

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