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

What each ingredient does

Milk
Forms the liquid base of the soup and gives it a creamy body.
Turnip
Cooked soft and mashed, it thickens the soup and gives it body and mild sweetness.
Flour
Thickens the soup when cooked with butter and milk, giving it a smoother texture.
Butter
Adds richness and fat, rounding out the flavor and smoothing the texture.

The step that matters

Mash very smooth through a colander. Cooked vegetables that are not pushed fully smooth leave a grainy, uneven texture. Thorough mashing breaks down the fibers so the soup becomes creamy when combined with the milk.

Swap the mace

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

  1. Parsleyfits better
  2. Cinnamonfits better
  3. Capersfits better
  4. Macethe original

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