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

What each ingredient does

Black beans
Form the main body of the soup and, once mashed, give it its thick texture.
Butter
Adds richness and flavor when melted with the flour as the base of the thickening.
Flour
Thickens the soup with the melted butter, giving it body as the stock is added.
Soup stock
Supplies the liquid that makes the soup and carries its savory flavor.
Sherry wine
Adds acidity and a mellow aroma when added to the soup in the tureen.

The step that matters

Mixing the butter, flour, and stock. Flour must be cooked briefly in melted butter and stock added gradually, or lumps form and the soup thickens unevenly.
