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

What each ingredient does

Flour
Thickens the sauce as it cooks with the liquid, giving it body.
Butter
Coats the flour so it blends smoothly and adds richness and fat to the sauce.
Milk
Forms the liquid base that the flour thickens into a pourable sauce.

The step that matters

Pour in the boiling milk gradually. Adding the hot liquid slowly while stirring keeps the flour dispersed, so the sauce thickens evenly without lumps.

Swap the parsley

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

  1. Cinnamonfits better
  2. Tarragonfits better
  3. Jalapenofits better
  4. Parsleythe original

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