spryte, can you post the recipe? My guess is it's asking for long gran rice. Most recipes that want you to use rice noodles usually refer to vermicelli noodles, cellophane is completely different. I've seen bean thread and cellophane used interchangeably though. Hope that helps.
They're talking about bean/cellophane noodles. Now that I have seen the recipe, I know exactly which dish your trying to make. I was in Hawaii earlier this year, at a luau at the polynesian cultural center and they had the dish you are making. Make sure not to use vermicelli noodles, this would be the wrong one. The bean/cellophane cook up clear and vermicelli are white (used a lot in Vietnamese cooking).
