Co-founder Alyssa Kearns hesitates to call “Nourish” a cookbook, because while it began as one and recipes dot its 122 pages, the stories told within aim to do far more than teach the reader how to prepare certain dishes. Kearns and co-founder Nica Sy are undergraduates at the University of Washington, and the book is the culmination of their two-quarter class with the Foster School of Business, Creating a Company.
