Why it works: Leek and parsnip match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 165 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
How to Make Broth for Soups
Ingredients
Directions
Place the beef and cold water in a stew pot.
Heat over low heat until it simmers gradually.
Skim off any scum that rises to the surface.
Once skimmed, add the salt and prepared vegetables.
Tie the vegetables together and drop them into the pot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef
- Provides the main flavor and gelatin-rich body as it slowly simmers in the water.
- Celery
- Adds aromatic flavor to the broth as it simmers.
- Leeks
- Add a mild onion-like sweetness and aroma to the broth.
- Carrot
- Adds subtle sweetness and color to the broth.
- Parsnip
- Adds earthy sweetness and body to the broth.
The step that matters
Heat gently and skim the scum. Heating slowly lets the water warm gradually so impurities and proteins rise as scum, which can be skimmed off for a clearer broth. Boiling too hard would emulsify fats and cloud the liquid.
Swap the celery
How well each one fits the dish's main ingredients (beef, leek, carrot, parsnip):
- Thymefits about as well
- Celerythe original
- Parsleyfits about as well
- Marjoramfits about as well
Fit is the average pairing score against beef, leek, carrot, parsnip. Candidates are from the same food group and used in at least 100 recipes.
