Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Peas
- Form the body and bulk of the soup once rubbed smooth.
- Milk
- Forms the creamy base of the soup.
- Flour
- Thickens the milk so the soup becomes smooth and creamy.
- Butter
- Adds richness and a silky mouthfeel to the soup.
The step that matters
Heating the flour-thickened milk. Flour must be mixed with cold milk first so it does not clump, and the mixture should be heated gently in a double boiler so it thickens smoothly without scorching or curdling.
Swap the peas
How well each one fits the dish's main ingredients (pepper, milk, flour, butter, egg):
- Almondfits better
- Walnutfits better
- Milletfits better
- Peasthe original
Fit is the average pairing score against pepper, milk, flour, butter, egg. Candidates are from the same food group and used in at least 100 recipes.
