Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef
- Provides the main meat flavor and chewy texture in the broth.
- Flour
- Thickens the soup as it cooks with the butter.
- Butter
- Carries fat for browning the flour and adds richness.
- Onion
- Adds aroma and savory sweetness as it softens in the broth.
- Rice or sago
- Releases starch that thickens the broth slightly.
The step that matters
Mix the flour with butter until light brown. Cooking the flour in fat browns it and removes its raw taste, while stirring prevents scorching. Stop once it is light brown so it thickens well without turning bitter.
Swap the celery
The recipe marks celery as optional. How well each one fits the dish's main ingredients (beef, rice, flour, butter, egg, onion, mace):
- Nutmegfits better
- Turmericfits better
- Cinnamonfits better
- Celerythe original
Fit is the average pairing score against beef, rice, flour, butter, egg, onion, mace. Candidates are from the same food group and used in at least 100 recipes.
