Peel and dice the ginger and onion. Peel and dice the sweet potatoes as well.
Heat the oil and fry the onion until translucent. Add ginger and sweet potatoes and fry for 2 minutes. Then pour in the broth, bring to the boil and let everything simmer for about 10 minutes. Then add the cream and puree everything. Let it boil again and season. Garnish with chervil.
Tip:
Finally, I add a freshly squeezed orange, which gives it a fruity, light note.
