Kosai, a deep-fat fried fritter made from cowpea, is an important product for economic development and poverty alleviation. Kosai is sold as street food almost exclusively by women entrepreneurs who use the money they earn from selling kosai on savings and daily expenditures for their family. In addition, cowpea is the more important indigenous African legume and kosai production uses a significant amount of cowpea. Data was collected, via personal interviews, with about 400 vendors in three different cities in the West African country of Niger. Results revealed that vendors with more experience were more likely to be successful.
