What Is Joshinko
Joshinko is a fine rice powder made of Japanese short-grain, the same rice eaten at meals. It’s a gluten-free flour for dango, Kashiwa Mochi, kusa mochi (草餅), gyuhi (求肥), Zenzai (Oshiruko), and rice crackers. When used to make wagashi, the mochi/dumplings are chewy and doughy in texture compared to Shiratamako.
What Does It Taste Like
It has a mildly sweet taste, similar to short-grain rice.
Difference between Japanese rice flours
There are different types of Japanese rice flour, each with its own characteristics and textures.
- Mochiko (餅粉): AKA Japanese sweet rice flour, it consists of glutinous short-grain rice (mochi rice 餅米)
- Shiratamako (白玉粉): AKA sweet rice flour, it consists of glutinous short-grain rice (mochi rice 餅米) that undergoes a special processing called the wet meal method. It’s much more expensive than mochiko and has a more refined flavor and springy texture.
- Joshinko (上新粉): made of Japanese short-grain rice for eating (uruchimai 粳米)
