Mock Turtle Soup

Ingredients

Directions

Prepare the head

  1. Scald the calf's head with the skin on.

  2. Saw the head open and remove the brains.

  3. Tie the head in a clean cloth and boil it for about 30 minutes.

  4. Remove the head, strip the meat from the bones, and cut the meat into small square pieces.

  5. Soak the meat in cold water to keep it white, then drain it.

Make the soup

  1. Place the meat in a soup pot and cover it with veal stock.

  2. Boil gently until tender.

  3. In a separate pan, melt the butter, then add a few spoons of stock to prevent burning.

  4. Add the chopped ham, mushrooms, and parsley to the butter and cook briefly.

  5. Combine the butter mixture with the meat and stock.

  6. Season with salt, pepper, mace, allspice, cayenne, soy sauce, port wine, and mustard.

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

What each ingredient does

Calf's head
Provides the gelatinous meat and bones that give the soup its body and richness.
Butter
Carries the flavor of the ham, mushrooms and parsley and adds richness to the soup.
Lean ham
Adds savory, salty depth that builds the soup's meaty flavor.
Mushrooms
Add earthy umami flavor and a soft texture to the soup.
Veal stock
Forms the liquid base and carries flavor through the whole soup.

The step that matters

Adding stock to the butter before combining. Adding a few spoons of stock to the melted butter keeps the butter from burning and scorching the ham and mushrooms, which would give the soup a bitter, burnt taste.

Swap the mace
