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

What each ingredient does

Flour
Browning in the pan gives the soup a nutty, toasted flavour and thickens it with the butter.
Butter
Mixed with the browned flour to form a smooth paste, adding richness and fat.
Toasted bread
Adds body and soaks up the liquid, giving the soup substance.

The step that matters

Adding the boiling water gradually. Pouring the water in slowly while stirring continuously lets the flour and butter paste disperse evenly. Adding it all at once can leave lumps that are hard to smooth out.
