Unfortunately, the finely ground defatted rice bran is no longer manufactured – the last producer closed up shop recently. John Marshall (our instructor) still has a stash and allowed us to use it in class, but eventually a substitute needs to be found. We tried both pure glutinous rice paste and a mix of glutinous rice paste and regular rice bran (the kind you can buy in a health food store). The “regular” rice bran + glutinous rice flour produced a rather lumpy paste because the rice bran wasn’t as finely ground. The stencil it was used with didn’t have any super fine lines, and it worked well with that stencil – but again, I wonder whether it would be too lumpy for very fine details. More research needed!
