Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Dried lima beans
- Form the body of the soup as they soften and break down when sieved.
- Butter
- Adds richness and a smooth, rounded mouthfeel to the finished soup.
- Flour
- Thickens the soup, giving it body as it heats in the liquid.
- Milk
- Adds creaminess and softens the flavor of the soup.
- Tomato ketchup
- Adds sweetness and acidity, giving the soup a tangy note.
The step that matters
Stirring the flour and salt into the boiling soup. Flour clumps if it hits hot liquid unmixed. Stirring it in well while the soup boils lets the starch disperse evenly and thicken smoothly.
Swap the lima beans
How well each one fits the dish's main ingredients (milk, butter, onion, flour, carrot, tomato, ketchup):
- Beansfits better
- Chickpeafits better
- Chestnutfits better
- Lima beansthe original
Fit is the average pairing score against milk, butter, onion, flour, carrot, tomato, ketchup. Candidates are from the same food group and used in at least 100 recipes.
