Why it works: Turnip and parsnip match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 590 recipes. Both carry coumarin, which smells sweet, hay. The science ↓

Ingredients
Directions
Make the broth
Place the soup bone in a large pot and add the cold water.
Heat over medium heat until it slowly comes to a boil, skimming off any foam.
Simmer gently for 4 hours.
Remove the meat and skim the broth again.
Finish and serve
Wash and dice the vegetables, then add them to the soup.
Simmer for an additional hour, season to taste, and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Soup bone
- Releases flavor and gelatin into the water, giving the broth body and savory depth.
- Potato
- Adds starch that softens during simmering, thickening the broth slightly and adding body.
- Rice
- Releases starch as it cooks, helping thicken the broth.
- Carrot
- Adds natural sweetness that balances the savory broth.
- Onion
- Contributes aromatic sweetness and depth as it softens in the broth.
The step that matters
Skimming the foam. Foam carries impurities and proteins from the bones that can cloud the broth and taint its flavor. Skimming early and again after the meat is removed keeps the broth clear and clean-tasting.
Swap the onion
