I found the 2 flours at an asian store, after going to 2 other asian stores that were larger.The flours are in clear see-thru 1-lb packages. One with red letters that said RICE FLOUR. The other in the same packageing with green letters that said GLUTINOUS RICE FLOUR. Both from Erawan Marketing Co., LTD Bangkok. Phone number is (66-2) 881-4040 (auto 12 lines)All of that phone number is what is on the package. I have not called them. Everything on the package is written in both English and Thai Language. The way it was told to me is that you do not need to add any gums to the flour. Just use it in place of wheat flour in any recipe.
I don't know how fast I will try it so if anyone finds the flours and trys it please post results! I will do the same.
