Basel Flour Soup
Also known as: Basler Mehlsuppe
Basel toasted-flour soup with a clove-and-bay-studded onion.

About Basel Flour Soup
Swissmilk’s Basler Mehlsuppe combines browned flour with water and a bay-and-clove-studded onion. This Basel version uses Bratbutter, the clarified-butter option in the recipe.
Toasting gives the flour the nutty aroma described by the source, with nutmeg, salt and pepper seasoning the soup. Optional tomato purée and grated cheese add further flavour.
The soup has a smooth, thickened consistency after simmering. The studded onion is removed before hot service, with crisp bacon cubes and fried onions among the optional toppings.
