Mock Turtle Soup

Ingredients

Directions

Make the soup

  1. In a large pot, combine 2 gallons of water, the calf's head or veal shanks, cloves, allspice, pepper, salt, onions, tomatoes, and carrots.

  2. Cook until the meat is tender, then remove it, chop it finely, and return it to the pot.

  3. If needed, thicken the soup with a little browned flour.

Color and serve

  1. To enhance the color, burn ½ cup of sugar in a pan, mix it with 1 pint of boiling water, and pour it into the soup.

  2. Add the hard-boiled eggs and chopped lemon, stir well, and serve.

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

What each ingredient does

Calf's head or veal shanks
Provides the meat and gelatin that give the soup its body and rich mouthfeel.
Browned flour
Thickens the soup and adds a toasted, deeper flavor when used.
Sugar
Caramelized in a pan, it deepens the soup's color and adds a slight sweetness.
Lemon
Adds acidity that brightens the rich, meaty broth.
Hard-boiled eggs
Add richness and a soft texture to the finished soup.

The step that matters

Burning the sugar. Sugar darkens and turns bitter if it burns too far, so it should be taken to a deep amber and removed from heat before the boiling water is added. Adding the water carefully prevents the hot syrup from splattering.

Swap the onion

How well each one fits the dish's main ingredients (veal, clove, allspice, pepper, tomato, carrot, flour):

  1. Capsicumfits better
  2. Parsnipfits better
  3. Turnipfits better
  4. Onionthe original

Fit is the average pairing score against veal, clove, allspice, pepper, tomato, carrot, flour. Candidates are from the same food group and used in at least 100 recipes.
