Turtle Soup

Ingredients

Directions

Prepare the turtle

  1. Decapitate the turtle and let it drain head down in a tub.

  2. The next day, remove the undershell and meat, cut off the fins, and discard the intestines.

  3. Boil the shells, fins, and head briefly to remove the outer skin, then cool in cold water.

Make the stock

  1. In a stock pot, combine beef, veal, and water; bring to a boil and skim off scum.

  2. Add roasted fowls, carrots, turnips, onions, leeks, celery, and salt; simmer for 4 hours.

  3. Strain the broth and set aside for use.

Finish the soup

  1. Place cleaned turtle shells and fins in a pot, moisten with stock, and bring to a boil.

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 the shells and fins that flavour the soup.
Shin of beef
Releases gelatin and savoury flavour into the stock during long simmering.
Knuckle of veal
Adds gelatin and body, giving the stock a fuller, richer texture.
Partially roasted fowls
Add roasted, browned flavour and depth to the simmering broth.
Leeks
Contribute a mild onion-like sweetness and aroma to the stock.

The step that matters

Skimming the scum after the boil. Impurities and coagulated proteins rise to the surface as the liquid heats. Skimming them early keeps the broth clear and prevents off flavours from returning into the stock during the long simmer.

Swap the onion

How well each one fits the dish's main ingredients (beef, veal, carrot, turnip, leek, celery):

  1. Parsnipfits better
  2. Chivefits about as well
  3. Lettucefits about as well
  4. Onionthe original

Fit is the average pairing score against beef, veal, carrot, turnip, leek, celery. Candidates are from the same food group and used in at least 100 recipes.
