Hanamaruki's Liquid Shio Koji is a unique and convenient preparation of traditional shio koji. Hanamaruki makes shio koji, places it in a sake bag and then presses it to get only the enzyme-rich liquid which they have a patent for. You can use this to marinate meats, season broths or even add to meatballs or gyoza filling...basically, if you want to add umami to anything, use Liquid Shio Koji.  That's why we call it liquid gold. To marinate a protein, add 8 to 10% of the weight of the protein in liquid shio koji. In other words, to marinate 100 grams of meat, add 8 to 10 grams of liquid shio koji. About the producer: Hanamaruki Foods is a large miso manufacturer founded almost 100 year ago. Their unique preparation of shio koji is wonderful for adding umami to many dishes.
