Ox- Tail Soup

Ingredients

Directions

Prepare the meat and vegetables

  1. Cut the ox-tails into pieces at the joints.

  2. Fry the ox-tails in a little butter with the gravy beef, carrot, turnip, onions, leek, celery, sweet herbs, and bay leaf.

  3. Add 1 pint of water and 1 teaspoon of peppercorns; stir until the pan is glazed.

  4. Fill the stewpan with 3 quarts of water, stirring occasionally.

Simmer the soup

  1. When it boils, reduce heat and let it simmer until the tails are tender.

  2. Remove the tails and trim them.

Finish and serve

  1. Cut the turnip and carrot into fancy shapes, about 2 cups total, and add 2 dozen button onions and a head of celery.

  2. Boil the vegetables in a little of the soup until tender.

  3. Strain the soup through a fine cloth, add the vegetables and ox-tails, and season with salt and lump sugar.

  4. For a thicker soup, add a little brown roux.

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

What each ingredient does

Ox-tails
Release gelatin and rich meaty flavor into the broth as they simmer slowly.
Gravy beef
Adds deep beefy flavor and body to the stock during long simmering.
Onions
Frying them builds sweet, browned savory notes that deepen the soup's flavor.
Brown roux
Thickens the soup and adds a toasted, nutty depth of flavor.

The step that matters

Frying the ox-tails and vegetables. Browning in butter creates caramelized flavors through the Maillard reaction, which give the broth its depth. Pale frying produces a flatter, weaker soup.

Swap the onion

How well each one fits the dish's main ingredients (beef, carrot, turnip, leek, celery, sugar):

  4. Onionthe original

Fit is the average pairing score against beef, carrot, turnip, leek, celery, sugar. Candidates are from the same food group and used in at least 100 recipes.
