Ox-tail Soup
Ingredients
Directions
Prepare the ox-tail
Cut the ox-tail into small joints and place them in a stewpan.
Cover with cold water, bring to a boil, and strain.
Dry the pieces of ox-tail, roll them in flour, and add them to the stewpan with the ham and sliced vegetables and butter.
Fry until browned.
Simmer the soup
Add the stock, herbs, peppercorns, cloves, and salt.
Boil and skim well.
Cover and cook gently for about 4 hours.
Strain the soup, remove the fat, and return it to the stewpan.
Finish and serve
When boiling, add the sherry and cornflour mixed smoothly. Stir and cook for a few minutes.
Serve the smaller pieces of the tail in the soup.
The remaining pieces can be reheated in a good brown sauce and served as an entrée.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ox-tail
- Provides rich meat flavour and gelatine that gives the soup body as it simmers.
- Butter
- Fat for frying that promotes browning of the ox-tail and vegetables, adding savoury flavour.
- Cornflour
- Starch that thickens the strained soup when cooked at a boil.
- Sherry
- Adds acidity and aromatic sweetness to finish the soup.
- Onions
- Sliced vegetables that add sweetness and aroma as they brown and soften.
The step that matters
Adding the cornflour. Cornflour must be mixed smoothly with a little liquid first, then added to a boiling soup. Stirring while it boils lets the starch swell evenly and thicken without lumps.
