Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beans
- Form the body of the soup, thickening it when cooked and rubbed smooth.
- Butter
- Adds richness and a smooth, silky mouthfeel to the soup.
- Milk
- Adds creaminess and dilutes the bean base into a smooth, pourable soup.
The step that matters
Rub the beans through a colander. The beans must be cooked fully soft first; undercooked beans will not pass through the colander smoothly and will leave a grainy texture in the soup.
Swap the onion
The recipe marks onion as optional. How well each one fits the dish's main ingredients (beans, butter, milk, pepper):
- Potatofits better
- Capsicumfits better
- Tomatofits better
- Onionthe original
Fit is the average pairing score against beans, butter, milk, pepper. Candidates are from the same food group and used in at least 100 recipes.
