【Miso】Rice & Kinzanji & Bread miso making workshop

My name is Haruko and I am the founder of The Koji Fermenteria. We specialise in koji; growing koji and making various forms of traditional Japanese ferments, such as miso, soy sauce, sake and rice vinegar. We also explore unconventional ways of using koji to uncover delicious and healthy applications yet to be found. While I love everything that involves koji, I find miso to be by far the most versatile ferment which enriches my everyday cooking!

Miso is a unique food ingredient packed with all five tastes; sweet, salty, bitter, sour and umami. It has a long history in Japanese food culture and our ancestors deeply appreciated it as a valuable source of protein (The Japanese only started to eat meat in the last few centuries). It also contributed to add umami and depth of flavour in an otherwise bland and humble diet. In recent years, chefs around the world have started to be leveraging the merits of miso and are now keen to include it in their recipes as a hidden natural flavour enhancer.


In this unique workshop you will learn a wealth of information about miso (basics of miso, its historical and cultural background, miso’s fermentation mechanism and, of course, how to make miso in the most trouble-free way and how to look after it during the fermentation etc). I will be sharing miso-making tips and secret techniques which I have acquired through my years of experience in miso-making.


You will be making approx. 1kg of organic rice miso using freshly made koji, which I will prepare especially for this workshop. On top of this, you will make special miso called Kinzanji which  ferments vegetables using rice, barley and soybean koji. This is very special!! As if this is not still enough, you also make bread miso using bread koji which you made in your earlier koji class.


You will also have a miso tasting session where you can taste and compare various kinds of miso; as well as miso soup made with dashi prepared following an authentic Japanese method. Miso soup will be accompanied by Japanese tsukemono pickles and onigiri!
