Vegan Basel Flour Soup
Basel Flour Soup is a beloved traditional soup from Basel, Switzerland, historically served at the annual Basel Carnival. It has a rich, nutty flavour from slowly toasted flour, blended with warm vegetable stock and finished with a sprinkle of grated plant‑based cheese. This fully vegan version preserves every bit of its comforting, deep flavour and smooth texture — simple, humble, and deeply satisfying.
