Mock-turtle Soup

Ingredients

Directions

Prepare the head

  1. Get the calf's head cleaned from the butcher, or wash it if uncleaned.

  2. Place the head in a pot with cold water.

  3. Boil briefly to loosen the hair. Scrape off the hair.

  4. Split the head. Clean it thoroughly.

  5. Remove the brains.

  6. Put the head in a pot with enough water to cover it. Skim frequently as it heats.

  7. Boil gently for 2 hours.

Make the soup

  1. Remove the head.

  2. Cut the meat into 1-inch pieces. Slice the tongue. Set aside the meat.

  3. Add the hough of beef, knuckle of veal, broken bones, onions, sliced carrot, turnip, sweet herbs, and whole peppers to the same water.

  4. Boil the brains separately. Pound the brains. Add the brains to the pot.

  5. Let the soup boil slowly for 4-5 hours.

Finish

  1. Strain the soup.

  2. Cool to remove the fat.

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-rich meat and bones that give the soup body and a rich mouthfeel.
Hough of beef
Adds beefy depth and collagen that thickens the broth during long simmering.
Knuckle of veal
Contributes gelatin and bone flavour, giving the stock body and a silky texture.
Brains from the calf's head
Pounded and added to the pot, they enrich the soup and thicken it slightly.
Onions
Build savory sweetness and aromatic flavour as they soften in the simmering broth.

The step that matters

Skim frequently as it heats. Skimming removes coagulated proteins and scum that would otherwise cloud the broth and add off-flavours. Clearing them early keeps the soup clean-tasting.

Swap the turnip

How well each one fits the dish's main ingredients (beef, veal, onion, carrot, pepper):

  1. Potatofits about as well
  2. Capsicumfits about as well
  3. Tomatofits about as well
  4. Turnipthe original

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