Roast Ducks

Ingredients

Directions

Prepare

  1. Draw, clean, and wash the ducks.

  2. Stuff one duck with a mixture of bread crumbs, hard-boiled egg yolk, minced sage, and minced onion.

  3. Rub the inside of the other duck with melted butter, pepper, and salt.

Roast

  1. Place both ducks in a roasting pan and pour boiling water over them.

  2. Roast for about 1 hour, basting frequently.

  3. In the last few minutes, dredge with flour and baste with butter to brown.

Make the gravy

  1. Chop the giblets finely.

  2. Pour off excess fat from the gravy in the roasting pan, thicken the remaining gravy with browned flour, and stir in the giblets.

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

What each ingredient does

Ducks
Provide the main meat, whose fat bastes and flavours the bird as it roasts.
Bread crumbs
Absorb juices and fat in the stuffing, keeping it moist and giving it body.
Hard-boiled egg yolk
Binds the stuffing and adds richness and a smooth, crumbly texture.
Melted butter
Carries seasoning over the skin and promotes browning and a rich flavour.
Flour
Browns in the rendered fat and thickens the gravy.

The step that matters

Dredging with flour and basting with butter at the end. Flour browns quickly in hot fat, so added too early or left too long it can scorch and turn bitter. Adding it in the last few minutes lets the skin brown evenly while the flour toasts.

Swap the onion

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

  1. Shallotfits better
  2. Chivefits better
  3. Capsicumfits better
  4. Onionthe original

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