When the beans are tender, prepare the stir-fry: fry 1 tbsp hing in oil, fry 15 dkg flour, and when off the heat add 3 tbsp red pepper, then add cold water and a large glass of sour cream to make a creamy mixture and whisk until smooth. Stir in the soup and finally season to taste with chopped parsley greens, grated smoked cheese, a little sugar and lemon juice. To serve, add sour cream and ground chilli to taste. Lentil soup can be prepared in the same way.
