Mock Turtle or Calf's-head Soup

Ingredients

Directions

Cook the head and feet

  1. Place the calf's head and pig's feet in a large pot and cover with 1 gallon of water.

  2. Boil for 3 hours until the flesh easily slips from the bones.

  3. Remove the head and continue boiling the feet.

  4. Cut the meat from the head, selecting enough fatty portions to fill a teacup, and set aside to cool.

  5. Remove the brains and set aside.

  6. Chop the remaining meat and tongue finely, then season with salt, pepper, marjoram, thyme, cloves, mace, allspice, and nutmeg.

  7. Return the seasoned meat to the pot with the pig's feet and boil slowly for 2 more hours.

  8. Let the soup cool overnight.

Finish and serve

  1. An hour before serving, warm the stock and strain it carefully.

  2. Cut the reserved meat into small squares and add to the soup.

  3. To make force-meat balls, mash the yolks of 5 hard-boiled eggs into a paste, adding the brains, butter, and salt.

  4. Mix in the beaten eggs and form into balls the size of pigeon eggs.

  5. Add the balls to the soup 5 minutes before serving.

  6. Stir in 1 tablespoon of browned flour mixed with cold water and let it boil.

  7. Add the juice of 1 lemon 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
Provides gelatin and meat that give the soup body and a rich texture.
Pig's feet
Release gelatin during long boiling, thickening the stock and giving it body.
Eggs
Bind the force-meat balls so they hold their shape while cooking.
Butter
Adds fat and richness to the force-meat balls.
Browned flour
Thickens the stock and adds a toasted, deeper flavor.
Lemon juice
Adds acidity that brightens the rich, heavy broth.

The step that matters

Adding the browned flour slurry. Flour must be mixed smoothly with cold water before it goes in, and the soup must then boil. Lumps form if flour meets hot liquid directly, and boiling is needed to fully cook the starch and reach full thickness.

Swap the mace

How well each one fits the dish's main ingredients (pepper, marjoram, thyme, clove, allspice, nutmeg, egg):

  1. Winter savoryfits better
  2. Cinnamonfits better
  3. Sagefits better
  4. Macethe original

Fit is the average pairing score against pepper, marjoram, thyme, clove, allspice, nutmeg, egg. Candidates are from the same food group and used in at least 100 recipes.
