Why it works: Celery and pepper match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 16,012 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Oxtail Soup
Ingredients
Directions
Prepare the broth
Cut the oxtail into small pieces.
Place the oxtail in a pot with the vegetables, onion, celery, water, and soup stock.
Bring to a boil, then reduce heat and let it simmer until the oxtail is tender.
Remove the oxtail pieces and strain the broth through a fine sieve to remove vegetable pulp.
Finish the soup
Add the roux to the strained broth and boil well together.
Stir in the sherry, return the oxtail pieces to the pot, and bring to a boil again.
Season with pepper, sugar, and salt to taste.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Oxtail
- Gives the soup its meaty flavour and body as it simmers into the broth.
- Roux
- Thickens the strained broth so it has a fuller, smoother body.
- Soup stock
- Adds savoury depth as the base liquid for the broth.
- Celery
- Contributes aromatic flavour to the broth during simmering.
- Sherry
- Adds a small amount of acidity and aroma to the finished soup.
The step that matters
Simmering the oxtail until tender. Oxtail is rich in connective tissue that needs long, gentle simmering to soften. Rapid boiling can toughen the meat and cloud the broth, so the heat should stay low once it has come to a boil.
Swap the onion
How well each one fits the dish's main ingredients (allspice, celery, pepper, sugar, sherry):
- Carrotfits better
- Capsicumfits better
- Mustardfits better
- Onionthe original
Fit is the average pairing score against allspice, celery, pepper, sugar, sherry. Candidates are from the same food group and used in at least 100 recipes.
