Mock Turtle Soup

Ingredients

Directions

Prepare the stock

  1. Clean and scald the calf's foot, then divide it.

  2. Place the foot, ham, onion, water, thyme, parsley, garlic, carrot, and turnip in a pan.

  3. Bring to a boil, remove the scum, and let it simmer for four hours with the cover on.

  4. Strain the stock and place the foot on a dish.

  5. Once the stock is cold, remove the fat.

Finish the soup

  1. Cut the meat from the foot into small pieces and add it back to the stock.

  2. Simmer gently for one hour.

  3. Mix the cornflour with two tablespoons of cold stock or water until smooth, then add to the soup.

  4. Bring to a boil while stirring continuously.

  5. Just before serving, add the sherry and a few drops of browning, if using.

  6. Season to taste with pepper and coarse sea salt.

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

What each ingredient does

Calf's foot
Supplies gelatine and body, so the stock becomes rich and slightly thick.
Cornflour
Thickens the soup as it heats, giving it a smooth, lightly glossy body.
Sherry
Adds acidity and aroma that brighten the rich stock just before serving.
Lean ham
Adds savoury, salty flavour to the stock during the long simmer.
Onion
Builds the savoury, aromatic base of the stock.

The step that matters

Cool the stock before removing the fat. Fat floats and sets solid when the stock is cold, so it can be lifted off cleanly. Skimming while hot leaves greasy droplets behind.

Swap the clove

How well each one fits the dish's main ingredients (ham, onion, thyme, parsley, garlic, carrot, turnip):

  1. Marjoramfits better
  2. Winter savoryfits better
  3. Celeryfits better
  4. Clovethe original

Fit is the average pairing score against ham, onion, thyme, parsley, garlic, carrot, turnip. Candidates are from the same food group and used in at least 100 recipes.
