Customer's Review

We received many compliments from customers. Thank you so much.

I tried to challenge myself to make the Salt Koji because I heard that it is easy to make.

Although it can be done easily, I was kind of worried whether the taste will be good or not.
But then I tried to use this product and it came out delicious.

It makes me to want to use it for various things.

I really like it!

Because Koji is not a solid type of food, it is easy to mix and super convenient.

You can just put both of the salt and Koji inside the honey container and shake it well.

Because I often use it for cuisine, the amount of shio Koji in the honey container is a good amount.

Up until now, I always put the Koji inside a Tupperware.

But I think the honey container is very good. I am so happy because not only that it is easy to mix the ingredients, it is also very hygienic.

This is my first purchase.

The special feature is the firm texture of the grains of Koji. Because it's a dried type of food, it's really helped me out that the expiration date is nearly one year.

It was also very easy to make prepare the Shio Koji using the honey container. Because the Salt Koji makes dishes tastier, I will use it for any dishes.

I will buy this product again.

Even thought it was my first time making Salt Koji, it was very easy to make as I followed the instruction.

It is certainly convenient to use the honey container. I think the quality of the Koji grains is also very good.

The instruction is very easy to understand.

In the first place, it’s also very simple and easy to make, and it’s taste delicious.

My favourite is pork. Just to dip it overnight makes it very delicious. I often eat it with vegetables.
