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

What each ingredient does

Potatoes
Provides the bulk and starchy body of the dish.
Milk
Forms the liquid base that thickens into a creamy sauce.
Butter
Adds richness and flavor, and its fat helps the sauce feel smooth.
All-purpose flour
Starch that swells in the hot milk and thickens it.

The step that matters

Stir until the milk thickens. Flour's starch needs to be stirred into hot liquid to swell evenly. Stirring keeps lumps from forming and stops the milk from scorching on the bottom of the pot.

Swap the parsley

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

  1. Parsleythe original
  2. Nutmegfits about as well
  3. Cinnamonfits about as well
  4. Thymefits about as well

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