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

What each ingredient does

Mushrooms
Provide the main body and earthy flavor of the soup.
Cream
Adds richness and a smooth, silky texture to the finished soup.
White stock
Forms the liquid base that carries the mushroom flavor.
Butter
Adds fat and flavor to the roux that thickens the soup.
Flour
Thickens the soup as a roux with the melted butter.

The step that matters

Stir in the flour without browning it. Flour cooked in butter thickens best when it stays pale; browning weakens its thickening power and changes the soup's flavor and color.
