Why it works: Milk and butter 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
- Lima beans
- Provide the main body and flavor of the soup when pressed into a purée.
- Milk
- Forms the creamy liquid base of the soup.
- Stock
- Adds savory depth to the liquid base.
- Butter
- Adds richness and flavor, and combines with flour to form a roux.
- Flour
- Thickens the soup as it cooks into the hot liquid.
The step that matters
Adding the butter-flour mixture to the hot liquid. If the flour and butter are not well rubbed together, or the mixture is added without stirring, lumps form and the soup thickens unevenly. Stirring while adding disperses the starch so it gelatinizes smoothly as the liquid heats.
Swap the lima beans
How well each one fits the dish's main ingredients (milk, veal, butter, flour, pepper):

Fit is the average pairing score against milk, veal, butter, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
