Cutting Down On Sugar? Try Ama-Koji | CoolJapan

Having a sweet tooth is both a blessing and a burden. After all, what comes with the saccharine pleasure to your palate is a potential threat to your health in the long run. But what if we tell you that there's a way to tone down on the sugar intake while still keeping your relationship with sweets? Try ama-koji

Similar to kombucha and kimchi where fermentation plays a huge part in its creation process, ama-koji is its sweet counterpart. This Japanese food processing method involves deriving the starch that comes from koji fungus, transforming it to glucose through heat. The end result becomes your new and healthier sweetener. While that sounds like complex chemistry, it's actually much easier than you think. 

How to make ama-koji

It all starts off with acquiring rice malt (koji) from your local supermarket. This ingredient is made from rice that's been cultured with the use of Aspergillus oryzae, a fungus often used in East Asian cuisine. This transforms the rice from solid to a liquid form, making it easier to mix in with other ingredients. This fermentation process allows the rice to enrich the food's amino and fatty acids, as well as elevate the flavour of sweetness. But this is only the first step. You'll also need a cooking thermometer as temperature plays a huge role in the next step.

After acquiring the rice malt, it's time to do some heating. Create a thin rice porridge as you usually do and pour in the rice malt. Make sure the rice malt is at room temperature before you start putting it in to maintain a steady temperature. Mix it with the rice porridge. Cover the mixture with a lid and let the rice malt warm up even more. Make sure you check in every so often, stirring the porridge and the malt ever so slightly, not allowing the temperature to go lower or exceedingly higher than 60 degrees Celsius. You can usually do so by keeping your rice cooker in the 'warm' setting.

It will typically take two to three hours, and you can usually tell by tasting once the ama-koji has fully fermented given its newly acquired sweetness. Some people leave it in the steady heat overnight to let it develop into its maximum its sweetness level, but you can make do with a couple of hours or so. 

Storage and use

According to some references, ama-koji can last in the freezer for a month. It can lose its sweetness the longer it's stocked after cooking, but heating it up again will revive its sweetness. In this duration, you can either eat it on its own as a treat or mix it in with tea, coffee, ice cream or just about anything you'd want to sweeten. It also doesn't spoil easily, given that it thrives on the enzymes it holds due to the fermentation process.

You can also dilute your ama-koji with hot water to create amazake (low alcohol sweet rice wine). Aside from becoming a refreshing drink that can be consumed either hot or cold, this also makes it easier to combine with any other food item you'd want to sweeten, replacing processed sugar. Both ama-koji and amazake can also be incorporated in cooking as a marinade or a seasoning. 

How is it better than sugar?

Aside from the ingredients being really accessible, it's also gluten, dairy, and technically, sugar-free. It's also rich in probiotics given its fermentation origin, making it healthy not just for your gut but also your holistic health (probiotic beauty, anyone?). To seal the deal further, it's also 100 per cent organic compared to artificial sweeteners found in the market today. Not to mention that you also get to play chemist (sort of), which we think is the coolest end of the stick here.
