Dive into the fascinating world of koji in this guided Japanese fermentation workshop from Long Beach Koji! Designed for home cooks, chefs, and curious foodies of all backgrounds, this hands-on experience introduces you to the traditional Japanese culture that helps create natural sweetness, rich aromas, and deep umami flavor.
You’ll learn how koji works and explore the role its enzymes play in transforming everyday ingredients into flavorful, nutrient-rich foods. Through guided tastings and sensory exploration, you’ll see, smell, and taste the ways fermentation can change simple ingredients.
Blending Japanese food culture, science, and hands-on learning, the workshop gives you a deeper understanding of what makes koji so special. You’ll explore the connection between koji and umami while learning how these traditional techniques can inspire the way you approach cooking at home.
Whether you’re already familiar with fermentation or hearing about koji for the first time, this welcoming workshop makes it easy to get curious and ask questions. Come ready to taste something new, learn about an ancient culinary tradition, and gain a fresh perspective on how fermentation can elevate everyday cooking!
You’ll also learn how to make Shio Koji (Salt Umami Koji) and take home half a pound of your own Shio Koji to use in your cooking.
