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

What each ingredient does

Onions
Are the main vegetable, becoming tender and sweet when boiled.
Cream
Provides richness and a smooth, moist texture for the sauce.
Flour
Thickens the cream into a sauce that coats the onions.
Butter
Adds fat for richness and a silky mouthfeel in the sauce.

The step that matters

Stir gently to combine and heat through. Flour in cream can clump or scorch if added to very hot liquid or stirred too hard. Gentle stirring over moderate heat lets the flour hydrate evenly and thicken the sauce smoothly.

Swap the onion

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

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

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