How to make Shio Koji


About recipe

Shio koji (塩麹) has a salty, savory, and slightly sweet taste, and is often used as a natural seasoning and tenderizer for meats, fish, and vegetables. It is also used in marinades, dressings, and sauces. Shio koji is said to have several health benefits, including aiding digestion, boosting the immune system, and promoting healthy skin.
