Turtle Soup, with Dried Turtle
Ingredients
Directions
Prepare the turtle and stock
Soak the turtle in warm water for two days, changing the water four times.
Simmer the turtle in a saucepan for one day.
Combine ham, shin of beef (cut into pieces), veal, soaked turtle, and water in a stock pot. Bring the mixture to a boil and skim the surface as it boils.
Add vegetables, herbs, and spices. Boil gently for eight hours.
Strain the soup through a fine sieve.
Clarify the soup
Cut the turtle into square pieces and set the pieces aside.
Remove fat from the cooled soup and place the fat in a saucepan.
Beat the egg whites and shells with a little cold water. Add the mixture to the soup and stir until it boils.
Simmer for 30 minutes until clear, then remove scum.
Strain through a napkin.
Finish and serve
Reheat the soup, adding lemon juice, salt, and turtle pieces. Bring the soup to a boil.
Add Madeira and caramel for color if desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Dried turtle
- Provides the main meat and the characteristic flavor of the soup.
- Eggs
- Whites and shells bind particles that cloud the stock, clarifying it as they cook.
- Shin of beef
- Releases gelatin and savory flavor into the stock during long simmering.
- Knuckle veal
- Adds gelatin and body, giving the stock a fuller, richer texture.
- Lean ham
- Contributes salty, savory depth to the stock.
- Lemon
- Its acidity brightens the finished soup and balances its richness.
The step that matters
Clarifying with egg whites. Stir gently until the mixture first boils, then keep the soup at a bare simmer. Vigorous boiling breaks up the egg raft, so it cannot trap the cloudy particles and the soup stays murky.
Swap the mace
How well each one fits the dish's main ingredients (ham, beef, veal, clove, pepper, egg, celery):
- Parsleyfits better
- Marjoramfits better
- Winter savoryfits better
- Macethe original
Fit is the average pairing score against ham, beef, veal, clove, pepper, egg, celery. Candidates are from the same food group and used in at least 100 recipes.
