Halve the cucumber lengthways. Remove the seeds and cut the cucumber into approx. 1 cm wide slices. Cook the cucumber slices in a little boiling salted water for 10-15 minutes.
Shape the sausage mixture into small balls and turn them in the flour. Fry the meatballs in clarified butter until golden brown and keep warm.
Finely dice the onions. Add butter to the frying fat and sauté the onions until translucent. Drain and add the cucumbers. Mix the cream and cornstarch together. If you are a little more calorie-conscious, you can replace the cream with milk. Pour the mixture over the onions and bring to the boil. Season the cucumber pan with salt, pepper and sugar. Finely chop the dill and mix with the cucumber along with the meatballs.
