Japanese flour

Rice flour

Rice flour "Shiratama ko"

Rice flour, also called "Kanzarashi," is made of glutinous rice.
In the old times it was produced in the depths of winter where people can get running water, but now we can manufacture the flour all year round.
First, we polish the glutinous rice, next, we put them into water until it becomes soft. Then we grind the glutinous rice together with water.
After that we de-water and compress it to make a white ball shape. The ball shape is made into smaller round shapes and dried. Rice flour with good quality should be white, shiny, completely dried and minute. When we boil the rice flour it becomes not only soft but also elastic.
The rice balls which don’t become hard when they are cooled after boiling are of good quality.
It has a smooth taste which is different from mochi, and it is typically used to wrap of sweets "gyūhi" and flour dumplings (shiratama dango), and are materials for high-quality Japanese sweets.

Mochi flour

Glutinous rice flour "Mochi ko"

We polish glutinous rice, soak it into water, grind it, and dry it to make Glutinous rice flour.
Sometimes non-glutinous rice and starch are added. It is used for making dumplings and the dumplings are glutinous and smooth. It takes fewer steps to make glutinous rice flour when compared to the number of steps to make rice flour and it costs less. Therefore there is a huge demand for mochi flour as material for Japanese sweets especially by manufacturer.

Dumpling flour

Dumpling flour "Dango ko"

We polish non-glutinous rice and glutinous rice, soak them in water, break them into pieces and dehydrate to make Dango flour.
Sometimes starch is added. The ratio of non-glutinous rice and glutinous rice combination is different. The more non-glutinous rice is added, the chewier becomes dumplings when compared to dumplings made with rice flour or mochi flour. Because Dumpling flour is not too soft, it is easy to make dumplings with it.

Joshin flour

Non-glutinous rice flour "Joshin ko"

We polish non-glutinous rice, soak them in water, break them into pieces and dehydrate them to make Non-glutinous rice flour. Because we do not use glutinous rice to make this flour, it is more suitable for making chewy dumpling. In family it is used for making "mitarashi", dumplings on a skewer with soy sauce and sugar and "kashiwamochi", a dumpling with bean jam inside wrapped in an oak leaf.
Manufacturers use non-glutinous rice flour as material for Japanese sweets and this flour is the most produced kind of rice flour.

Soybean flour

Soybean flour "kinako" / Green soybean flour "aokinako"

This flour is made of roasted soybeans. First we break the beans roughly and peel them. Then we grind them into pieces. There is also a kind of the flour that we make without peeling the beans. Usually yellow soybeans are used to make soybean flour, but the flour made of blue soybeans is called Green soybean flour "aokinako" or Bush warbler soybean flour "uguisukinako". The color is pale green and the scent of the flour is different from the yellow one. We use soybean flour for making Japanese sweets and making "abekawa mochi", a rice cake dusted with soybean flour. The flour contains starch, protein and fat and therefore is nourishing. The proteins in soybeans is certainly good in quality but hard to digest.
This problem is solved by processing soybeans, and powdered one such as soybean flour is more digestible than roasted soybeans and boiled soybeans.

Kashiwamochi flour

Flour for Kashiwamochi "Kashiwamochi ko"

We make this product only in certain season around the Boys’ Festival, 5th of May, for consumers who make Kashiwa dumpling, a dumpling which contains bean jam and is wrapped in an oak(Kashiwa) leaf. According to manufacturer, they sometimes put only non-glutinous rice flour (Joshin flour), or they sometimes mix starch such as potato starch into it. The reason of adding starch is because it makes the dumpling crispier so that it does not stick to the oak leaf, which wraps Kashiwa dumpling.
