Depending on how it's harnessed, koji can bring out the sugars in rice to be fermented into amazake (sweet rice porridge), mirin, and sake. Or it can denature the proteins in beans and grains to produce crazily savory miso pastes and soy sauces.
How does koji work?
The science of how koji works is a bit more complex than we have room to explore, but the main thing to understand is that its mycelial mat produces many enzymes, which work to break big molecules into smaller ones. The bigger molecules we’re talking about here are starches, carbohydrates, proteins and fats, and they are being reduced to simpler sugars, amino acids, fatty acid chains, etc. With what you know about fermentation and curing so far, you might be able to guess that these smaller molecules are prime nutrition for some other microorganisms (like our friend Lactobacillus), and in this way, koji lays a spectacular groundwork for natural fermentation processes to unfold. But, in tandem with other microbes, koji’s enzymes have their own added effects. For example, it has been found that typically tough cuts of meat can be cultured with koji spores; once the koji populates their surface and releases its enzymes into the meat, it radically tenderizes the cuts. Additionally, meat that is cured using koji has been shown to cure in at least a third of the time that meat cures using traditional charcuterie practice, due to the ongoing activity of koji’s enzymes during the curing process . It ‘s truly amazing.

How long to cook koji barley?
I like to check the temperature of my koji every few hours. It will take 36-40 hours at 88-90 degrees before the barley gets its fluffy white mycelial mat. For the first 24 hours, I keep the barley bundled in the towel, temping it with a meat thermometer every few hours to ensure it is keeping around 85-90 degrees. After 24 hours in the towel, I pull it out and dump the barley directly into the casserole pan, spreading it into an even layer. At this point, you may want to make a couple of furrows in the barley, to prevent the mix from overheating. Cover the pan with a towel and put it back in the incubator; then when you check the temperature every few hour s, you can move the fur rows to different places.
How to tell if koji is moldy?
Leaving the koji to incubate longer will cause it to mature to the point where it wants to produce spores. You can tell this is happening if the mold begins to turn olive green. If you want to use it for miso or sake, try to harvest it before it gets to this point. If it does start to turn green, that’s OK. You can still harvest it and use it to seed a future batch of grain.

How to incubate koji?
To successfully incubate koji, I needed to maintain an 86 to 90 degree environment with plenty of humidity . We decided that an immersion circulator mounted on a large bus tub heated to 95 degrees was an efficient way to meet both criteria. If I wrapped the whole setup to create a mostly closed environment, the ambient temperature above the water level was 88 degrees, and the abundance of water ensured plenty of humidity. I was flying blind here, since most modern setups for incubation were pretty janky themselves: Beer coolers, fridges, dehydrators, heating pads, and temperature regulators were all fair game. We wanted to test recipes using a setup that any home cook could rig, so we didn’t go for a muro— the hyper-traditional high-temperature, high-humidity incubation chamber that required hours of TLC.

What is koji in Japanese food?
As I talked about koji before in my soy sauce blog post, it is a type of edible mold culture made up of mostly of Aspergillus oryzae and is used to ferment soy sauce, miso, sake, and other common Japanese fermented foods. Although other Oriential culinary traditions use their own form of a koji-like mold, the Japanese have developed sophisticated methods of inoculating, fermenting, and collecting pure strains of the mold over the centuries, which has influenced many of their culinary traditions. Unlike other Aspergillus molds, which produce the carcinogen aflatoxin, Aspergillus oryzae is safe to use in food. To use koji, mold spores of the culture, known as koji-kin, are first used to inoculate cooked grains to grow the mold. 5

Researchers, cooks, chefs, and brewers alike are using koji grains to expand flavor profiles of recipes, ferment novel miso sauces, and even make whiskey. Members of the Nordic Food Lab team have played with roasting koji-permeated grains to create flavors ranging from soy sauce-like to chocolate, coffee, and caramel. 5 The flavors are formed from the Maillard reaction between free amino acids and sugars generated from the koji digestive enzymes and initiated from roasting. They have even used koji to ferment grasshoppers and moth larvae to create a rich and distinct insect ‘fish’ sauce. 6 Rich Shih of OurCookQuest.com recently outlined a way to ferment cheese and whey-based miso using koji. 7 Here, he took combined ricotta with fresh koji and salt, and fermented the mixture over one month to give a strong Parmesan flavor. By combining koji and salt with whey protein, he was able to create nacho cheese-like flavor with the same procedure. Both amateur and micro-distillers are invoking the power of koji to brew alcohol for distilling. For example, members of HomeDistiller.org have experimented with using koji to convert the starches in corn into free sugars, rather than standard methods such as adding commercial amylase, that can be used by brewing yeasts to produce alcohol. 8 The possibilities for koji are massive as more cooks and chefs experiment with this ancient mold.
