To Roast Ducks

Ingredients

Directions

The book gives no oven temperature. The 400°F in the steps was added when the recipe was transcribed, as a starting point.

Prepare the ducks

  1. Draw the ducks and stuff them with the shredded onion, sage leaves, salt, and pepper.

  2. Spit the ducks and dust them with flour.

Roast

  1. Baste the ducks with lard and roast them in a very hot oven (400°F / 200°C) for about 20 minutes.

  2. Just before removing them from the spit, dust them with flour and baste again.

Make the gravy and serve

  1. Prepare gravy using the gizzards and pinions, mace, peppercorns, catsup, and lemon pickle; strain it.

  2. Pour the gravy over the ducks and serve with onion sauce.

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

What each ingredient does

Lard
Fat that bastes the skin, helping it brown and crisp in the hot oven.
Flour
Dusted on the surface, it helps the skin brown and crisp during roasting.
Onion
Stuffed inside the birds, it adds aroma that gently scents the meat as it cooks.

The step that matters

Roasting in a very hot oven. High heat renders the duck's fat and crisps the skin, while regular basting keeps the surface from drying out. Too little heat leaves the skin flabby and greasy.

Swap the mace

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

  1. Marjoramfits better

  3. Parsleyfits better
  4. Macethe original

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