Getting to know koji for Chefs

“Getting to know koji for chefs” is unique comprehensive koji workshop for chefs who want to explore the full potential of koji. It is comprised of two-parts which take place in person on two separate days, usually with 1-2 week interval followed by 30 minutes online wrap-up session at the end.

My aim to host these workshops is

  • to make you feel even more motivated to use koji and explore its potential
  • to make you feel confident with making koji in your own environment

Contents overview

Part I focuses on the basic yet essential knowledge of koji and enzymes required to give koji a best chance to make food delicious. Then I will explain how best you can apply koji to your cooking. In order to make you prepared for more formal koji making in Part II, you will make koji using very simple method (utilising a small plastic bag and your body temperature). The class includes various experiments and tastings (3.0 hours onsite + 2 days online support for koji making)

Part II focuses on the practical koji making. This is a rare opportunity to be able to experience 48 hours of entire koji making in the space of 3+ hours. Employ your 5 senses and indulge in the enchanting world of koji making! What you will learn in this class is traditional Japanese (yet not overwhelming) method. I will explain the reason behind every steps. At the end of the class, you will bring home inoculated koji in small take away box and grow it in subsequent 48 hours with my support  (3.0 hours onsite + 2 days online support / troubleshooting for koji making)
 

30 minutes wrap up session can be arranged on mutually convenient day/time.
