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 ↓
Bone Soup
Ingredients
Directions
Make the broth
Wash the bones and chop or saw them into pieces.
Place the bones in a large saucepan and pour over the water.
Bring to a boil over high heat, skimming the surface well.
Add the salt, skim again, then reduce heat and let simmer for 2 hours.
Prepare the vegetables
Prepare the vegetables: chop the cabbage and place it in a basin of cold water.
Peel and dice the turnip, add it to the basin.
Scrape and slice the carrots, leek, and onion, and add them to the water.
Soak the barley in boiling water.
Finish the soup
After 2 hours, drain the vegetables and add them to the soup.
Drain the barley and add it as well, then stir in the pepper.
Let everything simmer for another 1½ hours.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Bones
- Release gelatin and flavour into the water, giving the broth body and richness.
- Barley
- Absorbs liquid and swells, thickening the soup and adding a chewy texture.
- Cabbage
- Adds bulk and a mild sweetness as it softens during simmering.
- Onion
- Contributes sweetness and savory depth as it cooks down into the broth.
- Carrots
- Add natural sweetness and colour, and soften into the soup.
The step that matters
Skimming the surface after boiling. Skimming removes coagulated proteins and fat that would otherwise cloud the broth and taste greasy, so it should be done thoroughly while the soup first heats and again after adding salt.
Swap the onion
How well each one fits the dish's main ingredients (cabbage, carrot, turnip, leek, pepper, barley):

Fit is the average pairing score against cabbage, carrot, turnip, leek, pepper, barley. Candidates are from the same food group and used in at least 100 recipes.
