Ox-Tail Soup, Clear
Ingredients
Directions
Prepare the ox-tail
Cut the ox-tail into 1-inch pieces and divide the thick part into four.
Wash the pieces and place them in boiling water for 15 minutes.
Drain and wipe the pieces with a soft cloth.
Make the soup
In a stewpan, combine the ox-tail, carrots, onion, parsley, thyme, celery, mace, salt, peppercorns, and water or stock.
Boil and remove the scum as it rises.
Simmer gently until the meat is tender.
Lift out the ox-tail pieces and strain the soup.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ox-tail
- Provides the meat and gelatin-rich connective tissue that gives the soup body and richness as it simmers.
- Water or clear stock
- Forms the liquid base in which the flavours from the vegetables and meat are extracted.
- Carrots
- Add natural sweetness and aromatic depth to the broth.
- Onion
- Adds savoury, aromatic flavour to the broth as it simmers.
- Celery
- Contributes aromatic, savoury flavour to the broth.
The step that matters
Removing the scum as it rises. Scum is coagulated protein and impurities that rise during boiling. Skimming it early keeps the broth clear and prevents bitter or muddy flavours from settling into the soup.
Swap the mace
How well each one fits the dish's main ingredients (carrot, onion, clove, parsley, thyme, celery):
- Marjoramfits better
- Winter savoryfits better
- Allspicefits better
- Macethe original
Fit is the average pairing score against carrot, onion, clove, parsley, thyme, celery. Candidates are from the same food group and used in at least 100 recipes.
