Why it works: Carrot and turnip 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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Roast-beef bone
- Releases gelatin and savory flavor into the water as it simmers, giving the broth body.
- Beefsteak
- Adds meaty, savory flavor to the broth during the long simmer.
- Turkey or chicken
- Contributes savory meat flavor and some gelatin to the broth.
- Carrots
- Add sweetness and color to the broth as they soften.
- Turnips
- Add mild sweetness and bulk, softening into the broth.
- Flour
- Thickens the strained soup as it boils, giving it a fuller texture.
The step that matters
Stirring the flour and water into the soup. Flour mixed directly into hot liquid clumps; whisking it first into cold water to a smooth slurry lets starch disperse evenly so the soup thickens smoothly.
