Turtle Soup

Ingredients

Directions

Prepare the turtle

  1. Kill and clean the turtle, then soak it in cold water.

  2. Wash and scrape the shell.

  3. Place the turtle in a soup kettle with two gallons of water and a hock of ham at 8 AM if serving at 3 PM. Boil briskly.

  4. Once the shell is hot, remove it, scrape out the meat, and return the meat to the kettle.

Make the soup

  1. At 11 AM, add the bag of thyme and sweet marjoram, along with 1 tablespoon of salt, pepper, and allspice.

  2. At 1 PM, add the juice of one lemon and remove the hock.

  3. Mix brown flour with some soup to thicken, then add it to the kettle, stirring constantly until it boils.

  4. Remove the bag of herbs, pour the soup into a tureen, and stir in 1 pint of sherry or Madeira wine.

Add the garnish and serve

  1. Slice the lemon and add it along with the yolks of four hard-boiled eggs.

  2. Chop some turtle meat, season with salt and pepper, mix with bread crumbs, and form into small cakes using the beaten yolks of two eggs.

  3. Fry the cakes in butter and place them on top of the soup 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 meat and body of the soup and the meat used for the fried cakes.
Brown flour (in the method)
Thickens the soup as it boils, giving it body.
Sherry or madeira wine
Adds acidity and aromatic depth stirred in at the end.
Eggs
Yolks bind the turtle meat cakes and enrich the soup with their flavor and richness.

The step that matters

Thickening the soup with flour. Flour must be mixed smoothly with some hot soup first and stirred constantly until it boils; otherwise it clumps and does not thicken evenly, because starch only swells properly once heated in liquid.

Swap the allspice

How well each one fits the dish's main ingredients (ham, pepper, lemon, egg, bread, butter, sherry):

  1. Parsleyfits better
  2. Thymefits better
  3. Marjoramfits better
  4. Allspicethe original

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