Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the body of the soup, as their starch thickens it when cooked and mashed.
- Milk
- Adds liquid and a creamy texture that makes the soup smooth and rich.
- Butter
- Adds fat for richness and a smooth, rounded mouthfeel.
The step that matters
Letting the milk boil. Milk scorches easily on the bottom of a pan and can boil over quickly. Once the milk is added, watch it closely and keep it moving so it does not burn or stick.
