Ox Tail Soup, Clear
Ingredients
Directions
Prepare the ox tail
Wash the ox tail pieces.
Boil the ox tail pieces in water for 15 minutes, then drain them.
Wipe the ox tail 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 the mixture and remove any scum that rises.
Reduce heat and simmer gently until the meat is tender, about 3 hours.
Lift out the ox tail pieces and strain the soup.
Clarify the soup if necessary.
Serve
Cut the additional vegetables into small shapes or thin shreds.
Simmer the vegetables in the clarified stock until tender.
Heat the ox tail pieces and serve with the soup poured over them.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ox tail
- Releases collagen and flavour into the stock, giving the meat body and a rich taste when simmered.
- Water or clear stock
- Acts as the cooking liquid that extracts flavour and gelatin from the meat and vegetables.
- Carrots
- Add gentle sweetness and aroma to the broth as they simmer.
- Celery
- Adds savoury, aromatic flavour to the broth during the long simmer.
- Onion
- Adds savoury depth and aroma; studded cloves add a warm, spiced note.
The step that matters
Simmer gently after the boil. A rolling boil makes the stock cloudy and can toughen the meat, so keep it at a gentle simmer. Skimming scum after the first boil keeps the soup clear.
Swap the onion
The recipe marks onion as optional. How well each one fits the dish's main ingredients (carrot, clove, parsley, thyme, celery, mace, beans):
- Parsnipfits better
- Turnipfits better
- Leekfits better
- Onionthe original
Fit is the average pairing score against carrot, clove, parsley, thyme, celery, mace, beans. Candidates are from the same food group and used in at least 100 recipes.
