Pull apart the sauerkraut and chop it up a little. Peel and core the apples. Peel the carrots and grate finely with the apples. Mix the grated with the sauerkraut. Immediately drizzle with lemon juice to prevent the apples from discoloring.
Peel the red onion, cut into fine strips and add to the salad. Mix the salad ingredients with the cream and sunflower oil and season to taste with iodized salt, white pepper and a little sugar. Arrange the salad on two plates.
