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

What each ingredient does

Green bananas
Starchy flesh that holds its shape and softens gently during simmering.
Milk
Provides the liquid for simmering and, reduced, forms the body of the sauce.
Butter
Fat that is melted with flour to form the roux that thickens the sauce.
Flour
Starch that thickens the melted butter and cooking liquid into a smooth sauce.

The step that matters

Stirring the liquid into the roux. Adding liquid to a roux all at once or without stirring can leave lumps of flour. Stirring steadily while it comes to a boil lets the starch swell evenly, giving a smooth, thickened sauce.

Swap the white pepper

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

  1. Cinnamonfits better
  2. Nutmegfits better
  3. Jalapenofits better
  4. White pepperthe original

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