Terre/Soil Soup

In a deep pan over high flame, heat oil and add burdock and soil and stir-fry. When strongly aromatic, add water and bring to boil. Reduce heat to low and gently simmer for 90 minutes. Transfer to a Thermomix and mix for 5 seconds. Pass through a large chinois, pressing with a ladle to strain out all liquid. Line a chinois with a coffee filter and strain liquid into a saucepot. Simmer liquid until 800 milliliters remain. Whip with an immersion blender and serve.
