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 ↓
Beef Broth
Ingredients
Directions
Prepare
Place the beef in a large pot and cover with cold water.
Set the pot over medium heat and bring to a boil.
Skim off any scum that rises to the surface.
Simmer
Once the scum is removed, add the carrots, turnips, leek, celery, parsley, bay leaf, and burnt onion.
Reduce the heat to low and simmer gently for at least 6 hours.
Ensure the broth cooks slowly without interruption.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef
- Releases flavour and gelatin into the water during long, slow simmering, giving the broth body.
- Carrots
- Add natural sweetness and aromatic flavour to the broth as they cook.
- Leek
- Adds a mild, savoury onion-like aroma to the broth.
- Celery
- Contributes aromatic, savoury flavour to the broth.
- Burnt onion
- Adds deep colour and a roasted, smoky aroma to the broth.
The step that matters
Skimming the scum. Scum is coagulated protein and impurities that rise as the water heats. Removing it before adding vegetables keeps the broth clear and clean-tasting rather than cloudy or greasy.
