I made salt koji with this dried koji and coarse salt

As the time passed, the homemade salt koji become more and more delicious. I like using this for making various cookings.

I like it so much that I finished using the dried koji so quickly

Because I finished using is so quickly, I think I'll buy it again in bigger amount.

This dried rice koji is slightly sweet.

I boiled the 150g of cooked rice and 900ml of water to the pot and put in the koji when the temperature reaches 60-degree Celcius. After I transferred it to the rice cooker and keeping the lid open for 10 hours in a warming mode, I can make amazake without fail.

So delicious!

It doesn't taste too strong and very tasty.

The homemade miso that I made using this koji has a certain deep taste to it.

It's so good I've made it countless times.

The product was packed very nicely and there's also an explanation on how to use it.

If my cooking goes well with this product, I'll definitely buy again.

The Difference Between Dried Koji and Regular Koji

Hand And Dried Koji

Dried koji is a type of koji that has been dehydrated. Koji can be divided into two types: regular koji (raw koji) and dried koji. Regular koji that is not dried is susceptible to various unwanted bacteria. It can also easily deteriorate in quality due to self-fermentation. Therefore, regular koji is harder to store. Because of that, dried koji was created.

Dried koji is very strong against various bacteria that have bad effects on the fermentation. It can also prevent self-fermentation. In addition to that, the taste of dried koji is pretty much the same as regular koji.
