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 salt 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.

WHAT YOU'LL EXPERIENCE:
1. The Koji Story
Learn the basics of Japanese fermentation and how Koji is used to create many beloved ingredients, including miso, soy sauce, sake, mirin, and vinegar.

2. Umami Tasting Experience
Discover how Koji transforms flavor through a guided tasting:
• Soy sauce vs. soy sauce koji with tofu
• Salt pickles vs. salt koji pickles
• Ama koji vs. sugar in traditional spinach goma-ae (sesame seed mix)
• Amazake (fermented sweet rice drink)
You’ll experience firsthand how fermentation enhances depth, sweetness, and umami. Steamed rice will be served.

3. Make Your Own Koji Seasonings
Each participant will prepare and take home:
• Salt Koji
• Soy Sauce Koji (or Tamari Koji with additional fee)
These will continue fermenting at home, and you’ll learn multiple fermentation methods using tools such as a yogurt maker, sous vide, or natural room-temperature fermentation
Ama (Sweet) Koji (Demonstration Only) - you’ll take home a ready-to-use batch to enjoy its natural sweetness right away.
