Green Turtle Soup

Ingredients

Directions

Make the soup base

  1. Chop the entrails, bones, and coarse parts of the turtle meat.

  2. Place the chopped parts in a pot with 1 gallon of water, sweet herbs, onions, pepper, and salt.

  3. Cook slowly for 4 hours.

  4. Simmer the fine parts of the turtle and green fat in ½ gallon of water for 1 hour.

  5. Strain the first soup and add the second mixture after 4 hours of boiling.

  6. Thicken the soup slightly with browned flour and simmer for another hour.

Make the force-meat balls

  1. Boil the eggs separately for 3-4 hours and add them to the soup before serving.

  2. If the turtle does not contain eggs, prepare force‑meat balls.

  3. Mix the yolks of 2 hard boiled eggs with 6 tablespoons of chopped turtle meat, butter, oyster liquor (if available), mace, cayenne, and sugar. Bind with a raw egg.

  4. Roll the mixture into small balls.

  5. Dip the balls in beaten egg, coat with cracker crumbs, and fry in butter.

Finish and serve

  1. Add the fried balls to the soup and finish with 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 meat
Provides the main flavour and body of the soup and the meat for the balls.
Green fat from turtle
Adds richness and a silky mouthfeel to the soup.
Browned flour
Thickens the soup slightly and adds a toasted, nutty note.
Hard boiled egg yolks
Add richness and bind the force-meat mixture into a soft, cohesive filling.
Raw egg
Binds the force-meat mixture so the balls hold their shape when fried.
Lemon juice
Adds acidity that brightens the rich soup and balances its fat.

The step that matters

Thickening with browned flour. Flour must be cooked and stirred in well so it thickens smoothly without lumps or a raw starchy taste; adding it to a boiling soup without stirring can clump it.

Swap the mace

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

  1. Parsleyfits better
  2. Thymefits better
  3. Turmericfits better
  4. Macethe original

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