Cooked http://bit.ly/exjmty Pudding 5 min in bain marie. Wasn't thick & tasted floury. Is asian tapioca flour same as non-?
It sounds like the flour wasn't cooked long or hot enough and didn't get a chance to thicken, so you may want to try cooking it longer. Unfortunately, we haven't tried this recipe using a traditional bain marie method -- it worked really well in the blender as written, which helped it whip up with a lovely lush texture.
