Turtle Soup

Ingredients

Directions

Make the herb base

  1. Combine winter savory, marjoram, lemon-thyme, parsley, green onions, green shallots, and mushroom trimmings in a pot with broth.

  2. Stew the herbs for about 1 hour, then strain through a fine sieve into a puree.

  3. Add the puree to the soup and season with crystallized cayenne pepper.

Cook the turtle

  1. Boil the turtle pieces and fins in the soup for 15 minutes, skimming off any foam that rises.

  2. Ensure the seasoning is balanced and adjust if necessary.

  3. Mould the quenelles into small balls, roll in flour, and poach them.

  4. Divide the turtle into four-quart basins, adding equal amounts of scalded fat and small quenelles.

Serve

  1. When ready to serve, warm the soup and add sherry and lemon juice before serving.

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

What each ingredient does

Turtle
Provides the main meat and gelatinous body of the soup.
Hard-boiled egg yolks
Bind the quenelle mixture and give it a soft, rich texture.
Hens fillets
Supply the delicate protein that forms the body of the quenelles.
Sherry or madeira
Adds aroma and a touch of sweetness and depth at the end.
Lemon juice
Adds acidity that brightens the finished soup.

The step that matters

Skimming the foam while boiling the turtle. Foam rising during boiling carries impurities that cloud the broth and spoil its flavour, so it must be removed as it forms.

Swap the onion

How well each one fits the dish's main ingredients (winter savory, marjoram, lemon, thyme, parsley, shallot, mushroom):

  1. Leekfits better
  2. Arrowrootfits better
  3. Chivefits better
  4. Onionthe original
