Science Wanted: kitchen powder identification edition

I have a large tupperware full of a crystalline white powder. It could be sugar, or it could be xylitol. How can I tell?
So far I've found two possible ways: burn it and record the energy per gram; feed it to dogs. I would prefer not to do the second, as xylitol kills dogs. I'm open to the first, if someone wants to link me to a good experimental method for such. But I'd really love a third way.
