Discover the foundation of Japanese fermentation in this hands-on class focused on Koji. You’ll learn how this traditional ingredient transforms simple foods into flavorful, gut-friendly staples.
Together, we’ll make and use Koji-based seasonings such as shio koji and explore how to incorporate them into everyday cooking. This class is perfect for beginners or anyone curious about fermentation, gut health, and authentic Japanese home cooking.
You’ll leave with practical knowledge, simple recipes, and the confidence to start using Koji in your own kitchen.
