1poundglutinous rice flourI found this at an international supermarket. The flour came in a 1 lb bag, which made it easy.
1/2cupred bean pasteI also found this at an international supermarket. They were out of the can, though, so I bought a bag of it from the refrigerated section. The clerk told me that it was the Japanese version of red bean paste, but that it would work just as well.
