Why it works: Carrot and celery match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 10,173 recipes. Both carry myristicin, which smells spice, warm. The science ↓
Ox-tail Soup
Ingredients
Directions
Prepare the soup
Skim off the fat from the cold soup.
The next day, cut the pressed meat into dice.
Flavor the soup with sherry and lemon juice, then simmer with the meat for 30 minutes.
If using egg balls, add them one minute before serving.
Brown and simmer
Cut the ox tail into pieces and fry in butter until browned.
Slice the onions and carrots, then brown them in the same pan.
Tie the browned onions and carrots in a bag with thyme and add to the soup pot.
Add the pieces of ox tail and the diced meat to the pot.
Grate the remaining carrots over the mixture and add four quarts of cold water, along with pepper and salt.
Boil for four to six hours, depending on the size of the tail.
Finish and serve
Strain the soup fifteen minutes before serving and thicken with browned flour.
Boil for an additional ten minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ox tail
- Releases collagen during long simmering, giving the soup a rich, full body.
- Lean beef
- Adds meaty flavor, and its browned surfaces deepen the savoriness of the broth.
- Browned flour
- Starch thickens the liquid as it heats, giving the soup a fuller texture.
- Sherry
- Adds aromatic depth and a mild acidity that brightens the broth.
- Onions
- Browning caramelizes their sugars, adding sweetness and savory depth.
- Carrots
- Add natural sweetness and body to the broth as they cook.
The step that matters
Thickening with browned flour. Flour starch only thickens fully when heated in liquid. Stirring it in smoothly and keeping the soup simmering lets the starch swell evenly, avoiding lumps and a thin, uneven texture.
Swap the lemon
How well each one fits the dish's main ingredients (beef, carrot, onion, thyme, celery, sherry, flour):
- Limefits about as well

- Cherryfits less well
Fit is the average pairing score against beef, carrot, onion, thyme, celery, sherry, flour. Candidates are from the same food group and used in at least 100 recipes.
