Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Vegetables: Form the main body of the soup and provide its texture and flavor once cooked until tender.
Milk or cream: Provides the liquid base and creamy richness of the soup.
Flour: Thickens the milk or cream so the soup becomes body-rich rather than watery.
Butter: Adds fat for richer flavor and helps the flour blend smoothly into the liquid.

The step that matters

Thickening the milk or cream with flour. Flour must be fully blended into the cold or warm liquid before heating; otherwise it clumps and does not thicken evenly. Bringing the mixture to a boil activates the starch so the soup thickens properly.
