Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Butter
Carries fat that coats the flour and adds richness and a rounded flavour.
Flour
Its starch swells in the hot liquid and thickens the sauce.
Curry powder
Provides the main spice aroma and flavour of the sauce.
Onion juice
Adds a savoury onion flavour that deepens the sauce.
Milk
Forms the liquid base that the thickened starch sets into a creamy sauce.

The step that matters

Slowly add the milk while stirring. Flour starch clumps when hit with cold liquid all at once. Adding the milk gradually while stirring disperses the flour evenly, so the sauce thickens smoothly without lumps.

Swap the onion

How well each one fits the dish's main ingredients (butter, flour, milk):

  1. Potatofits better
  2. Arrowrootfits better
  3. Leekfits better
  4. Onionthe original

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