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

What each ingredient does

Mashed potatoes
Provide the starchy base that gives the puree its body and smooth texture.
Flour
Thickens the milk mixture as it heats, giving the puree a fuller consistency.
Milk
Adds moisture and richness, loosening the puree to a creamy texture.
Onion
Adds savory aroma and depth as it softens in the cooking water.

The step that matters

Adding the milk and flour. Flour needs to be stirred in while the mixture heats so it dissolves evenly and thickens without lumps. Stirring continuously helps starch granules swell uniformly.

Swap the celery

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

  1. Parsleyfits better
  2. Thymefits better
  3. Garlicfits better
