3 Shio-koji Recipes

Koji refers to rice malt that has been treated with a type of fermentation culture, Aspergillus oryzae. Shio-koji is koji that has been fermented in salt. Yukari’s family, who hails from Chiba prefecture, has been in the rice malt business for over 50 years, so we are very familiar with Shio-koji. This is a very traditional ingredient but in recent times, not many people were using it in their cooking. However, three years ago, a leading magazine included Shio-koji in one of their features and this revived the ingredient’s popularity.

One of the reasons for Shio-koji’s popularity is that it comes with chockfull of health benefits. First, it contains plenty of amino acids, which help boost metabolism and also control the production of melanin in your body. Second, Shio-koji also includes kojic acid, which is high in antioxidants to help get rid of toxins in your body. Third, Shio-koji also helps activate the good bacteria in your intestines, which aids digestion and helps those with constipation issues.

Shio-koji can be used on a daily basis, and is a more healthful replacement for salt. It can also be used as a dressing as it comes with a unique umami flavour. Simply mix some olive oil with Shio-koji to create a fragrant salad dressing. Another way of enjoying Shio-koji is as a dip. Here’s how: Place some Shio-koji in a bowl and place a kitchen paper on top. Add a dollop of plain yogurt on top of the kitchen paper and let the liquid drip through to the Shio-koji. You now have a yummy dip for crackers or raw veggies.

For the recipes (on the facing page), we made use of Shio-koji in two different ways. With the chicken, we used Shio-koji as a marinade. Because Shio-koji comes with yeast, the proteins help keep the meat moist and juicy. The umami flavour of the Shio-koji also complements the chicken breast meat perfectly. As for field mustard, we deliberately chose this vegetable as it reminds us of Spring. Tempura is a traditional Japanese cooking method, but we gave it a modern twist by using skewers, which makes it easier to eat, especially at parties. With the salad, we used Shio-koji as a seasoning. Its refreshing flavour is reminiscent of Spring and pairs beautifully with the fresh sweetness of new onions and Japanese parsley. We hope you’ll enjoy!”
