Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.

What each ingredient does

Browned flour
Gives the soup its toasty, nutty flavour and colour.
Butter
Adds richness and helps the flour form a smooth paste.
Dry toast
Soaks up the broth, giving the dish body and a soft texture.

The step that matters

Pouring the paste into the boiling water. Stirring continuously while pouring disperses the flour paste evenly. Adding it slowly keeps lumps from forming, since flour clumps when it meets hot liquid all at once.
