Turtle Soup

Ingredients

Directions

Prepare the turtle

  1. Clean the turtle thoroughly and place it in a kettle. Cover with cold water and bring to a boil, skimming as necessary.

  2. Tie thyme, marjoram, and sweet basil in a small bag. Add the bag to the kettle and boil with the meat slowly for 20 minutes.

Simmer and finish

  1. Transfer the kettle to low heat and simmer for 5–6 hours.

  2. Remove the meat from the bones, dice it when cool, and return it to the stock.

  3. Season with salt and pepper to taste.

  4. Brown flour in the oven, blend it with butter, and thicken the soup to a creamy consistency.

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

What each ingredient does

Turtle
Provides the meat that becomes the main body of the soup.
Butter
Blended with browned flour to form a roux that thickens the soup.
Flour
Browned and blended with butter to thicken the soup to a creamy texture.

The step that matters

Simmer slowly on low heat. Long, gentle simmering breaks down the tough connective tissue of the turtle meat. Boiling hard can toughen the meat and cloud the stock.

Swap the basil

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

  1. Sagefits better
  2. Winter savoryfits better
  3. Parsleyfits better
  4. Basilthe original

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