Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green corn
- Provides the main body and sweet corn flavor of the soup.
- Milk
- Forms the liquid base and, with the flour, creates a creamy texture.
- Flour
- Thickens the soup as it cooks with the butter and milk.
- Butter
- Adds richness and carries flavor, and combines with flour to form a smooth thickening paste.
The step that matters
Stirring the flour and butter into the boiling milk. Flour lumps form if the paste is not mixed smooth before it meets the hot liquid, because starch on the outside of a clump gels before the inside can disperse. Blending the flour with butter and a little hot milk first, then stirring until smooth, lets the starch disperse evenly so the soup thickens without lumps.
Swap the onion
How well each one fits the dish's main ingredients (corn, milk, flour, butter):
- Potatofits better
- Capsicumfits better
- Sweet potatofits better
- Onionthe original
Fit is the average pairing score against corn, milk, flour, butter. Candidates are from the same food group and used in at least 100 recipes.
