Is rice flour just sticky rice flour?
No, sticky rice noodles generally refer to millet rice noodles, and some places are also called rhubarb rice. Some people also call glutinous rice flour sticky rice flour. Glutinous rice is white and sticky rice is yellow. I don't know what kind you are talking about. The general family food processor has the function of crushing, but it can't make sticky rice noodles because the crushed particles are not fine enough. It can only be done by a household pulverizer with special functions.
