Roast Ducks

Ingredients

Directions

Prepare

  1. Pluck the duck carefully without tearing the skin and remove all the plugs.

  2. Clean the inside thoroughly with warm water.

  3. Stuff the duck with butter, onion, sage, pepper, and salt.

Roast and serve

  1. Roast the duck in front of a brisk fire, but not too close.

  2. Baste frequently; cooking will take about 1 hour, depending on the age and size.

  3. When the breast plumps, the duck is done.

  4. Serve with a rich brown gravy.

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

What each ingredient does

Duck
Provides the meat and fat that render and flavour the dish as it roasts.
Butter
Adds fat and richness, helping keep the meat moist and tender during roasting.
Onion
Adds savoury sweetness and aroma as it cooks inside the bird.
Sage
Adds herbal aroma that flavours the duck from the inside.

The step that matters

Judging when the duck is done. Cooking time varies with the bird's age and size, so time alone can leave duck underdone or dry. Watching for the breast to plump signals doneness more reliably.

Swap the onion

How well each one fits the dish's main ingredients (butter, sage, pepper):

  1. Capsicumfits better
  2. Carrotfits better
  3. Sweet potatofits better
  4. Onionthe original

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