Salmi of Duck

Ingredients

Directions

Make the stock

  1. Put the duck bones and giblets in a saucepan and cover with hot water.

  2. When it boils, add the sliced onion, cloves, herbs, pepper, and salt.

  3. Cover and cook slowly for 1 hour.

  4. Strain the mixture and cool it to remove any fat that rises to the top.

Finish the soup

  1. Return the strained liquid to the heat, add the duck pieces, and simmer for another hour.

  2. If needed, add more water.

  3. In a separate pan, brown the flour and butter together, then stir into the duck mixture and let it boil.

  4. Add stewed green peas just before thickening, if desired.

Serve

  1. Arrange the duck on a platter and garnish with croutons or boiled rice.

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

What each ingredient does

Duck bones and giblets
Release flavour and body into the stock as they simmer.
Duck pieces
Provide the meat and rich, savoury flavour of the soup.
Onion
Adds aromatic sweetness to the stock as it cooks.
Flour
Thickens the liquid as its starch swells when heated with fat.
Butter
Adds richness and carries flavour, and cooks with the flour into a roux.

The step that matters

Browning the flour and butter, then stirring into the boiling soup. Cooking the flour in fat removes raw starch taste and helps it disperse. Stirring it in well and letting it boil lets the starch swell evenly, so the soup thickens smoothly without lumps.

Swap the peas

The recipe marks peas as optional. How well each one fits the dish's main ingredients (onion, clove, pepper, flour, butter, rice):

  1. Black-eyed peafits better
  2. Chickpeafits better
  3. Beansfits better
  4. Peasthe original

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