as google quickly revealed,

The iodine-starch test is a chemical reaction that used to test for the presence of starch or for iodine. The combination of starch and iodine is intensely "blue-black"

So, not baking soda.
Nope. The answer is corn starch. I2 + starch (potato starch is the best) gives an intense blue color.
