Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green peas
- Provide the main body, color, and sweet, vegetal flavor of the soup.
- Milk or cream
- Adds richness and a smooth, creamy mouthfeel.
- Butter
- Adds fat for a silky mouthfeel and a rounded, buttery flavor.
- Flour
- Its starch thickens the soup slightly as it heats.
The step that matters
Stirring in the milk or cream with the flour. Flour clumps if it is added directly to hot liquid, so whisk it smoothly into the dairy first. Dairy can also curdle or scorch if it boils hard, so keep the heat gentle during the 2-3 minute boil.
Swap the peas
How well each one fits the dish's main ingredients (onion, milk, butter, flour, pepper):
- Almondfits better
- Beansfits better
- Chestnutfits better
- Peasthe original
Fit is the average pairing score against onion, milk, butter, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
