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

What each ingredient does

Cauliflower: Forms the main body of the soup and gives it its bulk and mild flavor.
Butter: Fat that carries flavor and, with flour, thickens the broth smoothly.
Flour: Thickens the broth when fried with butter and blended into the liquid.
Sour cream: Adds richness and a tangy acidity that balances the vegetable flavors.
Parsley root: Contributes earthy, aromatic flavor to the broth as it boils.

The step that matters

Adding the flour and butter mixture. Flour must be fried in butter and thinned with hot liquid before adding, otherwise it clumps and leaves the soup lumpy instead of smoothly thickened.
