Ox-tail Soup
10 personsIngredients
Directions
Prepare the tails
Cut up the ox tails, separating them at the joints; wash them and put them in a stewpan with butter.
Cut the vegetables in slices and add them with peppercorns and herbs.
Put in ½ pint of water and stir over a sharp fire until the juices are drawn.
Simmer the soup
Fill the stewpan with water, and when boiling add salt.
Skim well and simmer very gently for 4 hours, or until the tails are tender.
Thicken and serve
Take the tails out, skim and strain the soup, thicken with flour, and flavor with ketchup and port wine.
Put the tails back, simmer for 5 minutes, and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ox tails
- Provide the meat and gelatinous body that flavours and enriches the broth as they simmer.
- Flour (in the method)
- Thickens the strained soup so it has body rather than running thin.
- Port wine
- Adds sweetness and depth of flavour to the finished soup.
- Ketchup
- Adds savoury, acidic depth to the soup's seasoning.
The step that matters
Simmer the tails very gently until tender. A rolling boil toughens and breaks up meat, while gentle simmering slowly dissolves connective tissue into gelatin, giving tender tails and a richer broth.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
