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 ↓
A Roast Beef and Boiled Turkey Soup
Ingredients
Directions
Make the broth
In a large soup pot, combine the turkey liquor, turkey bones, and beef bones.
Add the chopped carrots, turnips, onions, cloves, pepper, salt, and tomatoes if using.
Boil for 4 hours, then strain the mixture.
Thicken and serve
Return the soup to the pot and mix the flour with a little cold water.
Stir the flour mixture into the soup and bring to a boil.
Place the bread dice in the bottom of a tureen and pour the soup over it.
Add a little soy sauce for color.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the soup as it heats, giving it a fuller body.
- Bones of beef
- Release gelatin and savory flavor into the broth during long simmering.
- Bones of turkey
- Release gelatin and savory flavor into the broth during long simmering.
- Bread, cut into dice
- Soaks up broth in the tureen, adding body and a soft texture.
- Onions
- Add sweetness and aromatic depth as they cook down into the broth.
The step that matters
Mixing the flour with cold water before adding it. Flour added directly to hot liquid clumps, because its starch granules hydrate unevenly at the surface. Whisking it into a smooth slurry with cold water first lets it disperse evenly so the soup thickens smoothly.
Swap the tomato
The recipe marks tomato as optional. How well each one fits the dish's main ingredients (turkey, beef, carrot, turnip, onion, clove, pepper):
- Leekfits better
- Parsnipfits better
- Capsicumfits better
- Tomatothe original
Fit is the average pairing score against turkey, beef, carrot, turnip, onion, clove, pepper. Candidates are from the same food group and used in at least 100 recipes.
