The step that matters

Add some of the soup or milk to the paste to thicken the soup.. Adding hot liquid gradually to the flour and butter paste keeps it smooth and prevents lumps, because the starch granules disperse evenly before they swell and thicken the soup.

Swap the onion

  1. Potatofits better
  2. Leekfits better
