Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lima beans
- Provide the main body and flavor of the soup once pureed.
- Butter
- Adds richness and carries flavor when melted with the flour.
- Flour
- Thickens the milk into a smooth, creamy base as it cooks.
- Milk
- Forms the creamy liquid that the thickened base becomes.
- Onions
- Add savory sweetness and aroma to the puree.
The step that matters
Gradually add the milk, stirring constantly until boiling. Adding milk slowly while stirring keeps the flour evenly dispersed, preventing lumps. The mixture must reach a boil so the starch swells and thickens the soup.
Swap the lima beans
How well each one fits the dish's main ingredients (onion, parsley, butter, flour, milk):
- Chickpeafits better
- Almondfits better
- Cashew nutfits better
- Lima beansthe original
Fit is the average pairing score against onion, parsley, butter, flour, milk. Candidates are from the same food group and used in at least 100 recipes.
