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 ↓
Spring Vegetable Soup
Ingredients
Directions
Prepare the meat
Cut the meat from the bones of the shin of beef and knuckle of veal using a sharp knife.
Remove all fat from the meat and set it aside for other uses.
Break the bones in half and extract the marrow, setting it aside as well.
Place the meat and bones in a large stockpot or stewpan.
Simmer the broth
Add 5 pints of cold water and 1 teaspoon of coarse sea salt to the pot.
Cover the pot and bring it to a boil quickly.
Skim off any scum that rises to the surface with a spoon.
Reduce the heat and let the soup simmer gently for 5 hours.
Add the vegetables
Scrape and slice the young carrots.
Peel and slice the young turnip.
Wash the leek and celery, then cut them into squares.
Wash the cauliflower and add it to the pot along with the peas.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Shin of beef
- Long simmering breaks down its connective tissue, giving the broth body and tender meat.
- Knuckle of veal
- Bones and connective tissue release gelatin, adding body and richness to the broth.
- Cauliflower
- Holds its shape during simmering and adds mild bulk to the soup.
- Peas
- Add sweetness and soft texture to the finished soup.
The step that matters
Skim off the scum after boiling. Scum is coagulated protein and impurities that rise as the liquid heats. Removing it early keeps the broth clear and clean-tasting rather than cloudy or greasy.
Swap the peas

- Peasthe original
Fit is the average pairing score against beef, veal, carrot, turnip, leek, celery, cauliflower. Candidates are from the same food group and used in at least 100 recipes.
