'Kienyeji' simply means 'local' or 'free-range' in Swahili, and diners in Eldoret and Nakuru will pay a premium for it over broiler chicken for its firmer texture and deeper flavor.
Free-range indigenous chickens are cut up and slow-simmered with onions, tomatoes, and spices until the meat turns tender and the sauce thickens. Rift Valley eateries and market kitchens serve it with ugali, rice, or chapati.
