Why it works: Sage and thyme match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,485 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Ox-tail Soup
Ingredients
Directions
Make the stock
Cut the beef into pieces.
Place the beef in a pot with the cold water.
Bring the mixture to a slow boil, then simmer for 2 hours.
Brown the ox-tail and onion
Cut the ox-tail into joints and slice the onion.
In a pan, fry the ox-tail in butter.
Add the sliced onion to the pan and fry until golden.
Simmer and strain
Add the fried ox-tail and onion to the pot with the remaining vegetables, herbs, and cloves.
Let the soup simmer for 3 hours.
Strain the stock and set aside the pieces of ox-tail.
Skim the fat from the top of the stock and bring it to a boil.
Thicken and serve
For each quart of stock, mix 1 tablespoon of flour or cornflour with a little cold water.
Pour the boiling stock over the flour mixture, return to the pan, and stir until it boils.
Add the ox-tail back into the soup and heat until hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ox-tail
- Collagen from the bones and connective tissue gives the soup body and a rich, silky mouthfeel.
- Shin beef
- Slow simmering breaks down its connective tissue, adding gelatin and deep meaty flavour to the stock.
- Onions
- Frying until golden adds sweetness and browned, savoury flavour to the soup.
- Butter
- Fat used for frying the ox-tail and onion, promoting browning and carrying flavour.
- Flour or cornflour (in the method)
- Starch swells in the hot stock, thickening the soup to a lightly bodied consistency.
The step that matters
Thickening the stock. Flour must be mixed smoothly with cold water first, then whisked into boiling stock. Adding dry flour directly causes lumps, because starch clumps before it can disperse and swell evenly.
Swap the onion
How well each one fits the dish's main ingredients (beef, butter, carrot, turnip, celery, sage, thyme):
- Parsnipfits better
- Leekfits better
- Shallotfits about as well
- Onionthe original
Fit is the average pairing score against beef, butter, carrot, turnip, celery, sage, thyme. Candidates are from the same food group and used in at least 100 recipes.
