Scotch Broth

Ingredients

Directions

Make the broth

  1. Combine 4 ounces of pearl barley with 6 quarts of salt water and bring to a boil. Skim off any foam.

  2. Add salt beef or fresh brisket, a marrow bone or fowl, and 2 pounds of lean beef or mutton.

  3. Add a good quantity of leeks, cabbage, or parsnips, or use turnips, onions, and grated carrots if preferred.

  4. Keep boiling for at least 4 to 5 hours.

Finish and serve

  1. If using a fowl, add it just before serving.

  2. Serve the fowl separately if used.

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

What each ingredient does

Pearl barley
Thickens the broth as its starch releases during long simmering.
Lean beef or mutton
Adds meaty flavour and body to the broth as it simmers.
Marrow bone
Releases gelatin and fat during long cooking, enriching the broth's body and flavour.
Leeks, cabbage, or parsnips
Contribute sweetness and vegetable flavour that mellows during prolonged boiling.

The step that matters

Keep boiling for at least 4 to 5 hours. Tough cuts of meat and bones need long, steady simmering to break down connective tissue and release gelatin, which gives the broth body. Stopping early leaves the meat tough and the broth thin.
