Cut the sausages into pieces. Dice the onions and carrots and set aside.
Pour the oil into a large saucepan and let it get hot, then fry the sausages. Next are the onions. When these are translucent, add the carrots and fry for another 1 - 2 minutes. When everything is sweaty top up with approx. 1 liter of vegetable stock. Bring everything to a boil. After boiling for about 1 to 2 minutes, add 1 cup of rice. This takes about 10 minutes. After these 10 minutes, add the crème fraîche and continue cooking. Season to taste with pepper and thicken with a sauce thickener as required.
If you like, you can also use processed cheese instead of a sauce binder.
