Above is cooked basmati rice. Below is the reaction after adding several drops of iodine.
Glutinous Rice Flour
Here is some curry powder above mixed with water only. Below is the reaction when mixed with two drops of iodine.
The reaction was mild, not an inky blue black reaction, and so I'm not worried about it. This looks like it has some amylopectin (safe) and no significant amylose (unsafe).
