Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the broth into a lightly body-rich soup when mixed with cold water first.
- Toasted bread
- Soaks up broth at the bottom of the tureen, adding texture and body to each serving.
- Turkey bones
- Release gelatin and flavor into the long-simmered broth, giving it depth and body.
- Beef bones
- Add rich, savory meat flavor and body to the long-simmered broth.
- Carrots
- Add natural sweetness and aromatic depth to the broth as they soften during simmering.
- Onion
- Builds savory aroma and sweetness as it cooks down into the broth.
The step that matters
Mixing the flour with cold water before stirring it in. Flour dropped directly into hot liquid clumps, because its starch surface gets wet unevenly. Suspending it in cold water first lets the grains disperse, so the soup thickens smoothly when brought to a boil.
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.
