  1. Add the prepared vegetables, herbs, peppercorns, cloves, and mace. Cover.

  2. Cook slowly for about 3 hours.

  3. Strain the soup. Set the meat aside.

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

What each ingredient does

Ox tail
Provides the main meat and gelatin-rich body for the broth.
Egg whites
Attract and trap cloudy particles so the stock clears when clarified.
Sherry
Adds aroma and a mellow, slightly sweet depth to the finished soup.
Lemon juice
Adds acidity that brightens the flavor of the rich broth.
Lean beef
Adds meaty flavor and, with the egg whites, helps clarify the stock.

The step that matters

Skimming the scum and cooling to remove fat. Removing scum as it rises keeps the broth clean-tasting, and chilling lets fat solidify on top so it can be lifted off, leaving a clearer, lighter soup.

Swap the mace
