Preparation

• Heat the vegetable oil in a large soup pot set over medium-high heat. Salt the chicken pieces well, pat them dry and brown them in the oil. Don't crowd the pot, so do this in batches. Set the chicken pieces aside as they brown.
• Sauté the onions in the oil for 3-4 minutes, stirring often and scraping any browned bits off the bottom of the pot. Add the ginger and garlic and sauté another 1-2 minutes, then add the sweet potatoes and stir well to combine.
• Add the chicken broth, crushed tomatoes, peanut butter, peanuts, coriander and cayenne and stir well to combine. Add the chicken. Bring to a simmer and taste for salt, adding more if needed. Cover the pot and simmer gently for 90 minutes, or until the chicken meat easily falls off the bone and the sweet potatoes are tender.
• Remove the chicken pieces and set them in a bowl to cool. Remove and discard the skin if you want, or chop it and put it back into the pot. Shred the meat off the bones and put the meat back in the pot.
• Adjust the seasonings for salt and cayenne, then add as much black pepper as you think you can stand. Stir in the cilantro and serve by itself, or with simple steamed rice.
