Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Fat that combines with flour to form a roux, giving the soup a smooth, rich body.
- Flour
- Starch that thickens the milk into a smooth, creamy base when cooked with the butter.
- Milk
- Liquid base that, thickened by the roux, forms the creamy body of the soup.
- Spinach pulp
- Main vegetable that gives the soup its green color and earthy flavor.
The step that matters
Slowly add the cold milk while stirring. Adding cold liquid gradually while stirring keeps the flour from clumping, so the mixture becomes smooth rather than lumpy.
Swap the spinach
How well each one fits the dish's main ingredients (butter, flour, milk, cream):
- Potatofits better
- Leekfits better
- Arrowrootfits better
- Spinachthe original
Fit is the average pairing score against butter, flour, milk, cream. Candidates are from the same food group and used in at least 100 recipes.
