Our activities

 In order to accomplish our aspiration and mission, we are actively involved in various form of activities, such as having a stall at Stroud Green farmers market and selling homemade koji condiments, participating in educational events and providing consultation to restaurants. 

 However, our main focus is hosting in-depth koji workshops both online and offline which spans over days to weeks. Our approach toward workshops are known to be very experiential and gains high-level of satisfaction. Whereas koji is an extremely powerful tool as a cooking element, it is something that you need to build up and engrain experiences in your sense. It is not something you can learn by sitting, watching and listening. It also requires certain knowledge to make the most out of it. We design our workshops in a way you can gain confidence to deal with koji and optimise your setting on your own at the end of the class. We have a pride in providing such a course by deploying IT technology as best as we can.
