Why it works: Carrot and thyme match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 4,563 recipes. Both carry cuminaldehyde, which smells Spicy, cumin. The science ↓
Ox-Tail Soup
Ingredients
Directions
Brown the meat and vegetables
Cut the ox-tail into several pieces and fry them until brown in butter.
Slice the onions and carrots, then brown them in the same pan after removing the ox-tail.
Tie the browned onions and carrots in a bag with the thyme and drop it into the soup pot.
Make the soup
Add the pieces of ox-tail and the sliced beef to the pot.
Grate the two whole carrots over the mixture and add 4 quarts of cold water.
Season with pepper and bring to a boil.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ox-tail
- Browned in butter, it adds deep meaty flavour and body to the broth.
- Lean beef
- Adds meaty flavour and substance to the soup.
- Onions
- Browning them adds sweetness and savoury depth to the broth.
- Carrots
- Add natural sweetness and body to the soup.
The step that matters
Browning the ox-tail and vegetables. Browning caramelises the surface sugars and proteins through the Maillard reaction, creating deeper, richer flavour in the finished broth. Pale meat or vegetables will produce a flatter soup.
Swap the onion
How well each one fits the dish's main ingredients (beef, carrot, thyme, butter, pepper):

- Onionthe original
Fit is the average pairing score against beef, carrot, thyme, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
