This soup is very easy. Just put chicken leg in a pot, add in enough water. At first, use medium heat. After water gets boiled, turn to low heat. Cook for half an hour. Then add in shiitake and wolf berries. Cook for at least another half an hour. Add in salt and it’s done.
It actually took me one hour and a half to make this soup. Just the longer you cook it, the better it will taste.
