Why it works: Beef and leek work together. They rank in the top 6% of all ingredient pairs, and 659 recipes mention both. Both carry ethyl butyrate, which smells apple, fruity. The science ↓
The recipe
Ingredients
Directions
Make the stock
Combine beef and water in an iron pot.
Simmer for 4 hours, skimming frequently.
Remove beef from the pot.
Strain the stock.
Prepare the leeks
Wash and trim the leeks.
Cut the white part of the leeks into 1‑inch lengths and soak the white leek pieces in cold water.
Boil the green part of the leeks in the beef stock until pulpy.
Strain the green leeks through a fine sieve.
Cook and serve
Truss the fowl.
Place the fowl in a stewpan with the white leeks and stock.
Add salt and white pepper.
Bring the mixture to a boil.
Simmer gently for 1 hour.
Serve in a tureen or with the fowl separately, reserving a cup of soup to pour over the fowl.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lean beef
- Slowly simmered for hours to give the stock its body and rich flavour.
- Leeks
- Add savory flavour and, when the green parts are pulped, body to the soup.
- Fine young fowl
- Becomes tender through slow simmering and provides the main meat of the dish.
The step that matters
Boil the green part of the leeks in the beef stock until pulpy. Green leek must be cooked long enough to break down fully; underdone pieces stay fibrous and would not pass smoothly through the sieve, giving a gritty, uneven texture.

Fit is the average pairing score against beef, leek. 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).
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
