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):
- Parsleyfits better
- Cinnamonfits better
- Capersfits better
- 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.
