Ragout of Duck and Green Peas

Ingredients

Directions

Prepare the duck broth

  1. Cut the meat from the duck carcasses into neat slices.

  2. Stew the bones in 1 quart of water.

  3. Cool the broth. Skim the broth. Season the broth.

Make the gravy and peas

  1. Combine the gravy (or prepared broth) with the duck pieces in a saucepan. Heat the mixture without boiling.

  2. Cook the green peas in boiling water for 20 minutes. Drain the peas. Season the peas with pepper, salt, and butter.

  3. Thicken the gravy with a little browned flour mixed with cold water. Boil the thickened gravy briefly.

Serve

  1. Remove the duck from the saucepan. Arrange the duck in the center of a dish.

  2. Surround the duck with the peas like a green hedge.

  3. Pour the gravy over the meat.

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

What each ingredient does

Duck meat
Forms the main body of the dish, providing the savory meat that the gravy coats.
Browned flour
Thickens the gravy so it clings to the meat, and adds a toasted, nutty flavor.
Green peas
Add sweetness, color and a soft texture that contrasts with the tender duck.
Butter
Adds richness and a smooth mouthfeel to the seasoned peas.

The step that matters

Heat the duck gravy without boiling. Gently heating the meat in the gravy keeps the duck tender and stops the proteins from tightening and toughening. Boiling would make the meat dry and chewy.

Swap the peas

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

  1. Almondfits better
  2. Walnutfits better
  3. Chestnutfits better
  4. Peasthe original

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