Blue Star® Mochiko Sweet Rice Flour

Blue Star® Mochiko Sweet Rice Flour is unique among all varieties of rice flour due to its starch composition of nearly pure amylopectin. This characteristic makes it very viscous and useful as a superior, gluten-free thickening agent. Our flour has been milled on our farm since the 1940s and composed of California farmed, pure, unadulterated short grain sweet rice. No additives of any kind are added. Mild and neutral in flavor, popular Japanese applications include homemade microwave mochi, manju, chi-chi-dango, and arare (rice crackers). Our milling facilities are dedicated exclusively to the production of rice products.
