Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Forms the creamy liquid base that gives the soup its body and smooth mouthfeel.
- Flour
- Thickens the soup as it cooks, giving it a smoother, heavier texture.
- Butter
- Adds richness and fat, rounding out the flavour and smoothing the texture.
- Bananas
- Provide sweetness, body and a mellow banana flavour when mashed into the soup.
The step that matters
Rubbing the butter and flour together until smooth. Flour clumps if added raw to hot liquid. Working it smooth with the butter first lets it disperse evenly, so the thickening is lump-free.
Swap the banana
How well each one fits the dish's main ingredients (milk, flour, rice, butter, nutmeg):
- Coconutfits better
- Raisinfits better
- Vanillafits better
- Bananathe original
Fit is the average pairing score against milk, flour, rice, butter, nutmeg. Candidates are from the same food group and used in at least 100 recipes.
