Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Kidney beans
- Provide the main body and starch that thicken the soup when mashed.
- Butter
- Adds fat and richness, giving the soup a smoother mouthfeel.
- White wine
- Adds acidity and a bright, fresh flavour at the end.
The step that matters
Stir in the white wine before serving. Acid is added at the end so its bright flavour stays fresh; boiling it for a long time would drive off much of the wine's aroma and sharpness.
Swap the kidney beans
How well each one fits the dish's main ingredients (butter, pepper, white wine):
