Sunday, February 18th, 2024 from 10am-3pm in New Paltz


“To me, making miso is a ceremony. I like to make them with friends and family, so the miso can listen to our laughs and feel our hands while we are mixing. It is a relationship I create with food and people around me. Everybody’s miso tastes different, depending on their state of life, and environment and that’s the beauty of 'homemade.' Our life and love gets infused in Miso. Sometimes they taste so sweet and mild, sometimes they taste really salty or even sour! They all taste really good in different ways. I love giving my miso away as a gift because they are an extension of me.”

- Fumiha Tanaka

About This Class

Miso has been a Japanese staple ingredient for centuries. Miso is made using Koji, Aspergillus Oryze, which is also used to create many other important Japanese ancestral foods such as soy sauce, mirin, and sake. In this workshop, we will explore the intimate dialogue we can create with Koji, a sacred living mold that has been protected and handed down over generations from our ancestors.


Fumiha will introduce ways to use Koji in everyday life, and teach you how to make delicious miso at home. You will spend the day engaging in discussion, tastings, and hands-on learning, and you will leave with homemade miso and new recipes to try!


This knowledge share includes:

  • Brief history of koji and miso from a Japanese perspective.

  • Introduction to how koji is made.

  • Ways to incorporate koji into daily life and practice spiritual connection to food.

  • Demonstration of preparations and steps to make miso without plastic.

  • Tastings of various kinds of miso.

  • Tastings of other things made with koji (Amazake, koji pickles, koji water…etc)

  • Tips on making miso soup.

  • Handouts with instructions.
