Old-fasiitoned Mock Turtle

Ingredients

Directions

Make the stock

  1. Remove the brain and wash the head.

  2. Pour in 9 quarts of cold water and bring to a gentle boil.

  3. Skim the surface clean and boil for 1.5 hours.

  4. Remove the head and add 8 pounds of browned neck of beef, ham, onions, herbs, lemon, peppercorns, and salt.

Simmer and strain

  1. Stew gently for 7 to 8 hours, then strain the stock and cool it to remove the fat easily.

Finish the soup

  1. Remove the skin and fat from the head, cutting it into strips or dice.

  2. Add the meat to the stock.

  3. Thicken the stock with 4 ounces of butter mixed with 4 ounces of flour, mace, and cayenne.

  4. Stir in ½ pint of sherry and simmer for 1-2 minutes.

  5. Skim off any scum before serving.

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

What each ingredient does

Neck of beef
Gives the stock its meaty body and rich, savory flavor during long simmering.
Flour
Its starch thickens the stock once it is cooked with the butter.
Butter
Adds richness and helps the flour blend smoothly into the stock as a thickener.
Ham
Adds a salty, smoky savoury depth to the stock.
Sherry
Adds aroma and a touch of acidity to finish the soup.

The step that matters

Stew gently, then cool the stock before skimming fat. A gentle simmer keeps the stock clear instead of cloudy from vigorous boiling. Cooling the strained stock lets the fat solidify on top, so it can be lifted off cleanly.

Swap the mace

How well each one fits the dish's main ingredients (beef, butter, ham, onion, lemon, flour, pepper):

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

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