Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- White beans
- Provide the main body, and their starch thickens the soup as they cook and break down.
- Carrots
- Add gentle sweetness and help give the soup a fuller, more rounded flavor.
- Onions
- Build aroma and savory sweetness as they soften during the long simmer.
- Milk
- Adds creaminess and a soft, mellow sweetness from its natural milk sugars.
- Butter
- Adds fat for richness and a smooth, velvety mouthfeel.
The step that matters
Adding the milk and boiling for an additional 15 minutes. Milk contains proteins and sugars that can scorch on the bottom of the pot or separate at a hard boil. Keep the heat controlled and stir so the soup stays smooth and creamy.
