Turtle Soup

Ingredients

Directions

Prepare the turtle

  1. Kill the turtle at night in winter or in the morning in summer, hang it by the hind fins, cut off the head, and let it bleed well.

  2. Separate the bottom shell from the top shell.

  3. Put the liver and entrails in separate bowls of water.

  4. Cut the flesh from the bottom shell and place it in water.

  5. Break the bottom shell in two, wash it clean, and place it in a pot.

  6. Cover with water and add the bacon and chopped onions.

  7. Boil steadily for three hours, adding water if necessary.

  8. Wash the top shell and set it aside.

  9. Par-boil the fins, clean them, and cut them in half.

  10. Sprinkle salt over the fins and flesh from the shells and cover them.

Make the soup

  1. After boiling, remove the bacon, scrape the shell clean, and strain the broth.

  2. Reserve one-third of the broth in the pot and set the rest aside for the soup.

  3. Add the nice bits of turtle meat and the fins to the broth.

  4. Fill the upper shell with the mixture.

  5. Season with wine, cayenne pepper, mushroom catsup, lemon pickle, mace, nutmeg, and cloves.

What each ingredient does

Turtle
Provides the main meat and body of the soup, along with gelatin-rich flesh from the shells.
Bacon
Adds smoky, salty fat to the broth as it simmers, deepening its flavour.
Onions
Release sweetness and aromatic flavour into the broth during the long boil.
Mushroom catsup
Adds concentrated savoury depth and umami to the finished soup.
Wine
Adds acidity and aromatic richness that rounds out the seasoned soup.

The step that matters

Boiling steadily for three hours. A steady simmer, not a hard boil, slowly extracts flavour and gelatin from the bones and shell while keeping the meat tender. Adding water as needed keeps the pot from running dry and the broth from concentrating too much.

Swap the onion
