Peel the onion and cut into strips. Wash the chervil, shake dry, pluck the leaves from the stems and, except for something to garnish, chop. Remove the sausages. Fry the turnips, carrots and onion in sausage fat for about 5 minutes.
After 3 minutes dust with curry powder and flour. Add broth and milk while stirring. Bring to the boil and simmer for another 5 minutes. After about 3 minutes add sausage and chervil to the ragout. Season to taste with salt and pepper.
