Mock-Turtle or Calf's Head Soup

Ingredients

Directions

Simmer 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 slips easily from the bones.

  3. Remove the head.

  4. Let the pig's feet boil steadily.

Prepare the meat

  1. Cut the meat from the head, selecting enough fatty portions to fill a teacup.

  2. Set the meat aside to cool.

  3. Remove the brains and set aside.

  4. Chop the remaining meat and tongue finely.

  5. Season the chopped meat with salt, pepper, marjoram, thyme, cloves, mace, allspice, and nutmeg.

Finish and rest

  1. Return the seasoned meat to the pot with the pig's feet.

  2. Remove the pig's feet, leaving the gelatinous meat in the pot.

  3. Let everything boil slowly for 2 more hours without removing the cover.

  4. Remove the soup from the heat.

  5. Let the soup sit overnight.

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

What each ingredient does

Calf's head
Provides rich meat and gelatin that give the soup body and a thick texture.
Pig's feet
Release gelatin during long simmering, adding body and a silky mouthfeel to the broth.
Fatty meat from the head
Adds richness and fat, carrying the spices and giving the soup a rounded flavor.
Marjoram
Adds a warm, herbal aroma that seasons the chopped meat and broth.
Thyme
Contributes earthy, herbal aroma that complements the meat and spices.
Cloves
Add a strong, warm aroma that deepens the spiced flavor of the soup.

The step that matters

Boil slowly without removing the cover. Gentle, sustained simmering dissolves collagen into gelatin for body while keeping the broth clear. A hard boil or lifting the lid can make it cloudy and reduce the liquid unevenly.

Swap the mace
