TOIRO welcomes Mr. Nakaji Minami Tomoyuki, the Koji and fermentation master and also the founder of Koji Academy, to guide you to the magical world of Koji. Koji is a type of mold/ fermentation culture, and is the mother of Japanese essential fermented foods and drinks, such as soy sauce, miso, rice vinegar, sake, and ama-zake, to name a few. The event will focus on Sake-Kasu, which is the lees left over from the production of sake and is highly nutrient. This Koji product is full of flavor has been used in a wide variety of Japanese dishes and drinks for centuries.

The workshop will start with the presentation about Koji and Sake-Kasu by Nakaji Sensei and tasting of homemade Koji products. The second half of the class will be the cooking demonstration of special Sake-Kasu theme dishes by Nakaji Sensei and Naoko, and we will enjoy the meal together. And, of course, there will be donabe dishes! Each guest will take home a recipe packet and a souvenir.
