In a pot with butter cook diced onion until translucent, add washed chanterelle mushrooms (larger ones preferably cut) and peeled and halved garlic. Fry stirring occasionally for about 7 - 10 minutes.
Add peeled and diced potatoes and grated peeled carrot. Pour hot broth, add turmeric and bring the whole thing to boil.
Lower heat, cover and cook for about 15 - 20 minutes, until potatoes are soft. At the end add dill and chives, season with freshly ground pepper.
Add tempered sour cream to the pot with soup, mix and remove from heat.
