Japanese Koji making and fermentation culture workshop for professionals

A Japanese koji-making and fermentation culture workshop for professionals. This is an extremely rare chance to learn from koji expert Mr. Nakaji from Japan!

Koji is a key ingredient in Japanese cooking. It's used to make fermented Japanese ingredients such as miso, soy sauce, mirin, rice vinegar and sake. It's a type of mold which grows in steamed rice, creating full of enzymes. You, as a food industry professional, will be especially interested in the effects of enzymes which koji creates: it breaks down starches and proteins into sugars and amino acids. This technique is used in Japanese food to make fish and meat softer, and the taste richer.

With koji-making knowledge you can make authentic Japanese-tasting food and also make your own Japanese ingredients such as soy sauce, miso, mirin and sake. Perhaps more importantly, you can apply this technique to the western food as well!

In this koji making course we will cover:
• what koji is
• how to make koji (with demonstration)
• about the enzymes koji creates
• how to use koji in your food
• about Japanese fermentation food
• how to make/use miso, soy sauce, mirin, amazake and shio-koji
• about sake
-how to make it / different production methods / grades
-the many ways to drink sake
-how to use sake in your food

Mr. Nakaji the koji making expert is very famous in the Japanese fermentation world. He used to work at a traditional sake maker, and has been teaching koji making and Japanese fermentation culture all over Japan. We've finally managed to invite him to Sweden!
