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

What each ingredient does

Butter
Browning in the pan adds a nutty, toasted flavor and rich fat to the sauce.
Flour
Thickens the liquid into a smooth sauce as it cooks with the butter and water.
Water or stock
Forms the liquid base that the flour thickens into a pourable sauce.
Chopped olives
Add salty, briny flavor and bits of texture to the finished sauce.

The step that matters

Adding the water or stock slowly while stirring. Adding liquid gradually while stirring keeps the flour dispersed, so the sauce becomes smooth instead of lumpy.

Swap the onion

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

  1. Capsicumfits better
  2. Eggplantfits better
  3. Spinachfits better
  4. Onionthe original

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