Turtle Soup

Ingredients

Directions

Prepare the turtle

  1. Cut the head off the turtle and drain the body of blood.

  2. Cut the turtle into pieces: back, belly, head, fins, and intestines.

  3. Remove the gall without breaking it.

  4. Scald the turtle parts in boiling water to remove skin and shell.

  5. Cut the parts into neat square pieces and place them in cold water.

Make the soup

  1. Boil the back and belly in a little water until the bones are easily removed.

  2. Make a stock with the veal, ham, and turtle flesh, browning it well.

  3. Add water and the liquor from the boiled turtle to the stock.

  4. Work the butter and flour together, then add to the soup 10-12 minutes before serving.

What each ingredient does

Turtle
Forms the main body of the soup and provides its meaty texture and rich flavour.
Veal
Adds body and savoury depth to the stock.
Ham
Contributes salty, smoky flavour to the stock.
Butter
Adds fat and richness, carrying flavour through the soup.
Flour
Thickens the soup as it cooks with the butter, giving it body.

The step that matters

Adding the butter and flour. Flour mixed with butter must be stirred in and given time to cook, or it stays raw-tasting and can form lumps. Adding it only 10-12 minutes before serving leaves little time to cook out the starch and thicken evenly, so the soup should be stirred steadily while it simmers.
