After 20 minutes, check the soup for seasoning, adding salt and pepper as needed. Take a potato masher to break up the sweet potatoes and release their starch into the soup. Turn off the heat once you have reached the desired consistency and stir peanut butter into the soup.
Serve this soup either plain or with a dollop of sour cream and cilantro.
