Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Vegetable pulp
- Provides the main body, flavor and bulk of the soup.
- Butter
- Adds fat and richness to the soup's flavor and mouthfeel.
- Flour
- Thickens the liquid as it cooks, giving the soup a creamy body.
- Milk
- Adds creaminess and a mild, rounded sweetness to the finished soup.
The step that matters
Stirring in the butter and flour until smooth. If flour is added without being fully blended into the fat and liquid, it forms lumps that do not dissolve evenly. Stirring steadily while the mixture is hot keeps the starch dispersed so the soup thickens smoothly.
