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

What each ingredient does

Flour
Thickens the sauce when cooked with butter and liquid, giving it body.
Butter
Carries the flour and adds richness and flavor to the sauce.
Soup stock
Forms the liquid base that the flour thickens into a sauce.
Canned mushrooms
Supply the mushroom flavor and the main savory character of the sauce.

The step that matters

Cooking the flour in the butter. Cooking the flour until it turns brown develops nutty, toasted flavor and color. Stopping too early leaves a raw, pasty taste, while cooking too long can scorch it and make the sauce bitter.

Swap the white pepper

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

  1. Capersfits better
  2. Jalapenofits better
  3. Thymefits better
  4. White pepperthe original

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