Green Turtle Soup

Ingredients

Directions

Prepare the turtle

  1. Soak the turtle overnight to drain off blood.

  2. Cook the neck and flippers in boiling water for 1 minute to scrape off the scales.

Make the soup

  1. In a pot, combine shin beef, carrots, onion, whole peppers, cloves, thyme, leeks, celery, and parsley with enough water to cover.

  2. Boil for 1 hour.

  3. Add the turtle pieces to the pot, reserving the liquid.

  4. In a separate pan, melt the butter and stir in the flour to make a roux.

  5. Add the roux to the soup to thicken it.

  6. Simmer the soup until it loses its strong smell.

  7. Add the cut turtle and shin beef back into the soup.

Finish and serve

  1. Season with cayenne pepper and stir in the sherry.

  2. Serve immediately after adding the sherry.

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

What each ingredient does

Shin beef
Provides meaty body and rich flavour to the broth as it simmers.
Turtle
Supplies the main meat and gelatin that give the soup its body and texture.
Butter
Carries flavour and enriches the roux that thickens the soup.
Flour
Forms a roux with the butter that thickens the soup and gives it body.
Sherry
Adds acidity and aroma to finish the soup.

The step that matters

Simmer until the strong smell fades. Simmering lets volatile compounds from the meat and broth escape, so the soup tastes clean rather than strong. Stopping early leaves an off, gamey aroma that the sherry cannot fully mask.
