Why it works: Turnip and leek match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,046 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Grand Bouillon— General Stock
Ingredients
Directions
Start the stock
In a large stock pot, combine the beef, beef bones, veal knuckle, and chicken giblets.
Moisten with 5 gallons of cold water and set over low heat.
Once boiling, remove the scum and add 1 pint of cold water to help clear more scum.
Simmer and strain
When the stock is clear, add the salt and remaining ingredients.
Simmer gently for 4 hours, skimming off fat occasionally.
Strain the stock through a cloth and set aside for future use.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lean beef
- Gives the stock its deep, meaty flavour as it simmers.
- Cracked beef bones
- Release gelatin and marrow flavour, giving the stock body and richness.
- Veal knuckle
- Adds collagen that gives the stock a fuller, silkier body.
- Chicken giblets
- Add extra savoury flavour and depth to the stock.
- Onions
- Contribute sweetness and aromatic depth as they cook down.
The step that matters
Removing the scum at the start. Scum is coagulated protein and impurities that rise when the liquid first boils. Removing it keeps the stock clear and clean-tasting, so it should be skimmed before the stock is allowed to simmer.
Swap the onion
How well each one fits the dish's main ingredients (beef, veal, chicken, carrot, turnip, leek, celery):
- Parsnipfits better
- Onionthe original
- Chivefits about as well
- Lettucefits about as well
Fit is the average pairing score against beef, veal, chicken, carrot, turnip, leek, celery. Candidates are from the same food group and used in at least 100 recipes.
