Why it works: Turnip and carrot match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 8,002 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Vegetable Soup
Ingredients
Directions
In a large pot, combine cold water, pearl barley, shank bone or lean meat, coarse sea salt, turnip, and carrots.
Bring to a boil over medium heat, then reduce to a simmer.
Cook slowly for 2.5 hours.
About 30 minutes before serving, add the diced potatoes and any optional vegetables.
If the soup reduces too much, add boiling water to replenish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pearl barley
- Thickens the broth as its starch releases during long simmering, giving body to the soup.
- Shank bone or lean meat
- Releases flavor and gelatin into the broth during the long, slow simmer.
- Potatoes
- Soften and add starch that further thickens the soup and gives it substance.
The step that matters
Keep the simmer gentle and add potatoes late. A hard boil breaks down vegetables and makes the broth cloudy, while a slow simmer keeps the soup clear. Adding potatoes about 30 minutes before serving keeps them intact instead of dissolving into mush.
Swap the peas
The recipe marks peas as optional. How well each one fits the dish's main ingredients (barley, meat, turnip, carrot, potato):
- Beansfits better
- Lentilsfits better
- Chestnutfits better
- Peasthe original
Fit is the average pairing score against barley, meat, turnip, carrot, potato. Candidates are from the same food group and used in at least 100 recipes.
