Tip
The Basel recipe doesn't just taste good at carnival. A delicious soup for cold days. All you need is a little flour, stock, red wine and butter.
Careful stirring and long cooking are essential for a good flour soup. The soup becomes bitter if the flour is stirred unevenly. If it is blended for too short a time, the intense aroma is missing and the soup becomes unsightly gray.
