My wife is a very good cook on her own. She is very fond of cooking and love to cook, I want her to pursue a career in cooking not as a chef but may be having some own business like own cooking schools or catering system. For that I believe she needs to join any cooking school and do a course to get the basic idea of how to teach others as well as to understand the different aspects of cooking. Is my idea correct or how she can start something in the cooking career ?
