Heat the coconut milk cream in a saucepan. Add onions, ginger and curry paste, sweat for 3 - 4 minutes. Add the pumpkin cubes and potatoes and cook for 3 minutes.
Deglaze with coconut milk and vegetable stock. Cook the vegetables for about 30 minutes until they are soft, then puree and strain through a sieve.
If you like, you can add a few roasted pumpkin seeds to the soup and garnish with some fried ginger slices.
