How do I tell if it's tapioca starch or cornstarch?
Ok, I want to make pudding. I have a jar of a white powder that is either cornstarch or tapioca starch. The recipe calls for cornstarch and I thought I had figured out that it was cornstarch because I tried to see if I could make "oobleck" with it and it worked...but then I did some research and found out that you can make oobleck with tapioca starch too...So, can I just substitute tapioca starch into the recipe (it's a recipe for chocolate pudding, pretty much alton brown's recipe_? If not, how can I tell if it's tapioca starch or cornstarch?
