Mock Turtle Soup

Ingredients

Directions

Prepare the stock

  1. Place the cleaned calf's head in a soup pot.

  2. Add the soaked pickled pork, sweet herbs, onions, celery, truffles or morels, mace, and pepper.

  3. Fill the pot with water, leaving some space at the top, and boil slowly until the meat is tender.

  4. Remove the meat, cut it into square pieces, and break the bones, returning them to the pot.

  5. Let the soup simmer for 4 to 5 hours, then cool it quickly and remove the fat.

Finish and serve

  1. Strain the soup and thicken it with flour and butter.

  2. Add Harvey's sauce, sherry or Madeira, and lemon juice.

  3. Stir in the meat from the head and pork, and add egg balls or force-meat if desired.

  4. Warm the soup 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 the gelatinous body and rich flavour of the soup stock.
Flour
Thickens the strained soup together with the butter into a smooth body.
Butter
Enriches the thickened soup and adds richness with the flour.
Sherry or madeira
Adds acidity and aromatic depth to the finished soup.
Pickled pork
Adds savoury, salty depth to the stock.
Lemon juice
Adds acidity that brightens the rich, heavy broth.

The step that matters

Cooling and removing the fat before thickening. Rapid cooling lets fat rise and set on top so it can be removed cleanly. Leftover fat would make the finished soup greasy and heavy.

Swap the mace

How well each one fits the dish's main ingredients (pork, onion, celery, truffle, pepper, sauce, sherry):

  1. Thymefits better
  2. Parsleyfits better
  3. Garlicfits better
  4. Macethe original

Fit is the average pairing score against pork, onion, celery, truffle, pepper, sauce, sherry. Candidates are from the same food group and used in at least 100 recipes.
