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 beef
Cut all the meat from the beef and remove the fat.
Break the bones in half and take out the marrow.
Place the meat and bones in a large saucepan.
Add 5 pints of water and 1 teaspoon of salt.
Cover and bring to a boil quickly.
Skim off any scum that rises.
Reduce heat and let it simmer gently for 5 hours.
Add the vegetables
Scrape and slice the carrots.
Peel and slice the turnip.
Wash and chop the celery and leek.
Wash the cauliflower, soak in salted water for 2-3 minutes, then rinse and dry.
Remove green leaves and stalk, and break into sprigs.
Add the sliced carrots, celery, and leek to the soup an hour before serving.
After 30 minutes, add the sliced turnip.
After another 15 minutes, add the cauliflower sprigs.
Cook the peas
In a separate pot, bring water to a boil.
Add the shelled peas, 1 teaspoon of salt, and ¼ teaspoon of baking soda.
Boil the peas for 15-20 minutes until soft, then drain.

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 connective tissue, giving the broth body and rich flavor.
- Bones (in the method)
- Marrow and collagen release gelatin and depth into the broth during the long simmer.
- Carrots
- Add natural sweetness and hold their shape through the simmer.
- Turnip
- Contributes a mild, slightly peppery flavor and firm texture to the soup.
- Cauliflower
- Adds mild sweetness and a tender texture that softens in the hot broth.
- Baking soda
- Raises the pot's pH, helping the peas soften quickly and turn tender.
The step that matters
Skim off the scum after the boil. Foam that rises during the initial boil contains proteins and impurities; removing it keeps the broth clear and clean-tasting before the long simmer.
