Brush pumpkin well, divide, remove seeds and dice pumpkin flesh. Dice carrots as well.
Bring the vegetable stock to the boil. Add pumpkin and carrots and simmer covered for about 20 minutes. Then puree.
Squeeze oranges. Add the juice with the cream and the crème fraîche to the soup. Heat up again.
Season to taste with salt and pepper to taste. If you like, you can also sprinkle a few fresh herbs over it. The soup can also be frozen. After defrosting, however, you have to puree it again or whip it vigorously with a whisk, as the pumpkin flesh separates from the water when it is frozen.
