Making your own roasted rice for genmaicha

I’ve been experimenting and I think I finally found a workable recipe to make homemade genmai. You can read about it in my blog http://www.myjapanesegreentea.com/how-to-make-your-own-roasted-rice-for-genmaicha
Does anyone have a better recipe? Also for those who want to try it please tell me about your results. Thanks!
