Why it works: Fennel and turnip work together. They rank in the top 7% of all ingredient pairs, and 34 recipes mention both. Both carry coumarin, which smells sweet, hay. The science ↓
The recipe
Ingredients
Contains: wheat (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Make the broth
Simmer the sirloin and bones in the beef broth until the beef looks loose.
Transfer the beef to a deep vessel.
Strain the broth over the beef.
Let the broth cool with the fat on top to preserve it.
When ready to use, remove the fat from the broth.
Add the vegetables
Add the carrot, fennel, celery, leek, and turnips to the broth.
Simmer gently until the vegetables are tender.
Strain the vegetables out.
Serve
Serve the soup with large square pieces of toasted bread.
For a warm dish, reheat the beef in the soup and serve with the strained turnips and carrots.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sirloin and beef bones
- Release flavour and gelatin into the broth during long, gentle simmering.
- Carrot
- Adds natural sweetness and aroma to the broth.
- Celery
- Contributes aromatic flavour that builds the broth's savoury base.
- Turnips
- Add a mild, slightly sweet vegetable flavour and tender texture to the soup.
The step that matters
Simmer gently until the vegetables are tender. A gentle simmer cooks vegetables evenly and keeps the broth clear, whereas a hard boil breaks up vegetables and makes the broth cloudy.

Fit is the average pairing score against beef, carrot, celery, leek, turnip, bread. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
